### 0.18.0 <small>January 25, 2024</small>
|
||||
|
||||
- Added [#633](https://github.com/roboflow/supervision/pull/720): [`sv.PercentageBarAnnotator`](0.18.0/annotators/#percentagebarannotator) allowing to annotate images and videos with percentage values representing confidence or other custom property.
|
||||
|
||||
```python
|
||||
>>> import supervision as sv
|
||||
|
||||
>>> image = ...
|
||||
>>> detections = sv.Detections(...)
|
||||
|

||||
... scene=image.copy(),
|
||||
... detections=detections
|
||||
... )
|
||||
```
|
||||
|
||||
- Added [#702](https://github.com/roboflow/supervision/pull/702): [`sv.RoundBoxAnnotator`](/0.18.0/annotators/#roundboxannotator) allowing to annotate images and videos with rounded corners bounding boxes.
|
||||
|
||||
- Added [#770](https://github.com/roboflow/supervision/pull/770): [`sv.OrientedBoxAnnotator`](/0.18.0/annotators/#orientedboxannotator) allowing to annotate images and videos with OBB (Oriented Bounding Boxes).
|
||||
|
||||
```python
|
||||
import cv2
|
||||
import supervision as sv
|
||||
from ultralytics import YOLO
|
||||
|
||||
image = cv2.imread(<SOURCE_IMAGE_PATH>)

result = model(image)[0]
|

annotated_frame = oriented_box_annotator.annotate(
|
||||
scene=image.copy(),
|
||||
detections=detections
|
||||
)
|
||||
```
|
||||
|
||||
- Added [#696](https://github.com/roboflow/supervision/pull/696): [`sv.DetectionsSmoother`](/0.18.0/detection/tools/smoother/#detection-smoother) allowing for smoothing detections over multiple frames in video tracking.
|
||||
|
||||
- Added [#769](https://github.com/roboflow/supervision/pull/769): [`sv.ColorPalette.from_matplotlib`](/0.18.0/draw/color/#supervision.draw.color.ColorPalette.from_matplotlib) allowing users to create a `sv.ColorPalette` instance from a Matplotlib color palette.
|
||||
|
||||
```python
|
||||
>>> import supervision as sv
|
||||
|
||||
>>> sv.ColorPalette.from_matplotlib('viridis', 5)
|
||||

|
||||
```
|
||||
|
||||
- Changed [#770](https://github.com/roboflow/supervision/pull/770): [`sv.Detections.from_ultralytics`](/0.18.0/detection/core/#supervision.detection.core.Detections.from_ultralytics) adding support for OBB (Oriented Bounding Boxes).
|
||||
|
||||
- Changed [#735](https://github.com/roboflow/supervision/pull/735): [`sv.LineZone`](/0.18.0/detection/tools/line_zone/#linezone) to now accept a list of specific box anchors that must cross the line for a detection to be counted. This update marks a significant improvement from the previous requirement, where all four box corners were necessary. Users can now specify a single anchor, such as `sv.Position.BOTTOM_CENTER`, or any other combination of anchors defined as `List[sv.Position]`.
|
||||
|
||||
- Changed [#756](https://github.com/roboflow/supervision/pull/756): [`sv.Color`](/0.18.0/draw/color/#color)'s and [`sv.ColorPalette`](/0.18.0/draw/color/#colorpalette)'s method of accessing predefined colors, transitioning from a function-based approach (`sv.Color.red()`) to a more intuitive and conventional property-based method (`sv.Color.RED`).
|
||||
|
||||
!!! failure "Deprecated"
|
||||
|
||||
`sv.ColorPalette.default()` is deprecated and will be removed in `supervision-0.22.0`. Use `sv.ColorPalette.DEFAULT` instead.
|
||||
|
||||
|
||||
- Changed [#769](https://github.com/roboflow/supervision/pull/769): [`sv.ColorPalette.DEFAULT`](/0.18.0/draw/color/#colorpalette) value, giving users a more extensive set of annotation colors.
|
||||
|
||||
- Changed [#677](https://github.com/roboflow/supervision/pull/677): `sv.Detections.from_roboflow` to [`sv.Detections.from_inference`](/0.18.0/detection/core/#supervision.detection.core.Detections.from_inference) streamlining its functionality to be compatible with both the both [inference](https://github.com/roboflow/inference) pip package and the Robloflow [hosted API](https://docs.roboflow.com/deploy/hosted-api).
|
||||
|
||||
!!! failure "Deprecated"
|
||||
|
||||
`Detections.from_roboflow()` is deprecated and will be removed in `supervision-0.22.0`. Use `Detections.from_inference` instead.
|
||||
|
||||
|
||||
- Fixed [#735](https://github.com/roboflow/supervision/pull/735): [`sv.LineZone`](/0.18.0/detection/tools/line_zone/#linezone) functionality to accurately update the counter when an object crosses a line from any direction, including from the side. This enhancement enables more precise tracking and analytics, such as calculating individual in/out counts for each lane on the road.

# Detect and Annotate
|
||||
|
||||
Supervision offers a streamlined solution to effortlessly annotate predictions from a
|
||||
range of object detection and segmentation models. This guide demonstrates how to
|
||||
execute inference using the YOLOv8 model with either the
|
||||
[Inference](https://github.com/roboflow/inference) or
|
||||
[Ultralytics](https://github.com/ultralytics/ultralytics) packages. Following this,
|
||||
you'll learn how to import these predictions into Supervision for image annotation
|
||||
purposes.
|
||||
|
||||
## Run Inference
|
||||
|
||||
First, you'll need to obtain predictions from your object detection or segmentation model.
|
||||
```python
|
||||
import cv2
|
||||
from ultralytics import YOLO
|
||||
|
||||
model = YOLO("yolov8n.pt")
|
||||
image = cv2.imread("image.jpg")
|
||||
results = model(image)[0]
|
||||
```
|
||||
=== "Ultralytics"
|
||||
|
||||
```python
|
||||
import cv2
|
||||
from ultralytics import YOLO
|
||||
|
||||
model = YOLO("yolov8n.pt")
|
||||
image = cv2.imread(<PATH TO IMAGE>)
|
||||
results = model(image)[0]
|
||||
```
|
||||
|
||||
=== "Inference"
|
||||
|
||||
```python
|
||||
import cv2
|
||||
from inference.models.utils import get_roboflow_model
|
||||
|
||||
model = get_roboflow_model(model_id="yolov8n-640", api_key=<ROBOFLOW API KEY>)
|
||||
image = cv2.imread(<PATH TO IMAGE>)
|
||||
results = model.infer(image)[0]
|
||||
```
|
||||
|
||||
## Load Predictions into Supervision
|
||||
|
||||
Now that we have predictions from a model, we can load them into Supervision. We can do so using the [`sv.Detections.from_ultralytics`](https://supervision.roboflow.com/detection/core/#supervision.detection.core.Detections.from_ultralytics) method, which accepts model results from both detection and segmentation models.

|
||||
=== "Ultralytics"
|

|
||||
model = YOLO("yolov8n.pt")
|
||||
image = cv2.imread("image.jpg")
|
||||
results = model(image)[0]
|
||||
detections = sv.Detections.from_ultralytics(results)
|
||||
```
|
||||
We can do so using the [`sv.Detections.from_ultralytics`](/latest/detection/core/#supervision.detection.core.Detections.from_ultralytics) method, which accepts model results from both detection and segmentation models.
|
||||
|

|

|

image = cv2.imread(<PATH TO IMAGE>)
|
||||
results = model.infer(image)[0]
|
||||
detections = sv.Detections.from_inference(results)

|

## Annotate Image
|
||||
|
||||
Finally, we can annotate the image with the predictions. Since we are working with an object detection model, we will use the [`sv.BoundingBoxAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.BoundingBoxAnnotator) and [`sv.LabelAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.LabelAnnotator) classes. If you are running the segmentation model [`sv.MaskAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.MaskAnnotator) is a drop-in replacement for [`sv.BoundingBoxAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.BoundingBoxAnnotator) that will allow you to draw masks instead of boxes.

# count people in zone
|
||||
|
||||
## 👋 hello
|
||||
|
||||
This demo is a video analysis tool that counts and highlights objects in specific zones
|
||||
of a video. Each zone and the objects within it are marked in different colors, making
|
||||
it easy to see and count the objects in each area. The tool can save this enhanced
|
||||
video or display it live on the screen.
|
||||
|
||||

||||
|
||||
## 🛠️ script arguments
|
||||
|
||||
- ultralytics
|
||||
|
||||
- `--source_weights_path` (optional): The path to the YOLO model's weights file.
|
||||
Defaults to `"yolov8x.pt"` if not specified.
|
||||
|
||||
- `--zone_configuration_path`: Specifies the path to the JSON file containing zone
|
||||
configurations. This file defines the polygonal areas in the video where objects will
|
||||
be counted.
|
||||
- `--source_video_path`: The path to the source video file that will be analyzed.
|
||||
- `--target_video_path` (optional): The path to save the output video with annotations.
|
||||
If not provided, the processed video will be displayed in real-time.
|
||||
- `--confidence_threshold` (optional): Sets the confidence threshold for the YOLO model
|
||||
to filter detections. Default is `0.3`.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model. Default is `0.7`.
|
||||
|
||||
- inference
|
||||
|
||||
- `--roboflow_api_key` (optional): The API key for Roboflow services. If not provided
|
||||
directly, the script tries to fetch it from the `ROBOFLOW_API_KEY` environment
|
||||
variable. Follow [this guide](https://docs.roboflow.com/api-reference/authentication#retrieve-an-api-key)
|
||||
to acquire your `API KEY`.
|
||||
- `--model_id` (optional): Designates the Roboflow model ID to be used. The default
|
||||
value is `"yolov8x-1280"`.
|
||||
|
||||
- `--zone_configuration_path`: Specifies the path to the JSON file containing zone
|
||||
configurations. This file defines the polygonal areas in the video where objects will
|
||||
be counted.
|
||||
- `--source_video_path`: The path to the source video file that will be analyzed.
|
||||
- `--target_video_path` (optional): The path to save the output video with annotations.
|
||||
If not provided, the processed video will be displayed in real-time.
|
||||
- `--confidence_threshold` (optional): Sets the confidence threshold for the YOLO model
|
||||
to filter detections. Default is `0.3`.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model. Default is `0.7`.
|
||||
|
||||
## 📌 zone configuration
|
||||
|
||||
- `horizontal-zone-config.json`: Defines zones divided horizontally across the frame.
|
||||
- `multi-zone-config.json`: Configures multiple zones with custom shapes and positions.
|
||||
- `quarters-zone-config.json`: Splits the frame into four equal quarters.
|
||||
- `vertical-zone-config.json`: Divides the frame into vertical zones of equal width.
|
||||
|
||||
## ⚙️ run example
|
||||
|
||||
- ultralytics
|
||||
|
||||
```bash
|
||||
python ultralytics_example.py \
|
||||
--zone_configuration_path data/multi-zone-config.json \
|
||||
--source_video_path data/market-square.mp4 \
|
||||
--confidence_threshold 0.3 \
|
||||
--iou_threshold 0.5
|
||||
```
|
||||
|
||||
- inference
|
||||
|
||||
```bash
|
||||
python inference_example.py \

# heatmap and tracking
|
||||
|
||||
## 👋 hello
|
||||
|
||||
This script performs heatmap and tracking analysis using YOLOv8, an object-detection method and
|
||||
ByteTrack, a simple yet effective online multi-object tracking method. It uses the
|
||||
supervision package for multiple tasks such as drawing heatmap annotations, tracking objects, etc.
|
||||
|
||||
|
||||
## 💻 install
|
||||
|
||||
- clone repository and navigate to example directory
|
||||
|
||||
```bash
|
||||
git clone https://github.com/roboflow/supervision.git
|
||||
cd supervision/examples/heatmap_and_track
|
||||
```
|
||||
|
||||
- setup python environment and activate it [optional]
|
||||
|
||||
```bash
|
||||
python3 -m venv venv
|
||||
source venv/bin/activate
|
||||
```
|
||||
|
||||
- install required dependencies
|
||||
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
## 🛠️ script arguments
|
||||
|
||||
- `--source_weights_path`: Required. Specifies the path to the weights file for the
|
||||
YOLO model. This file contains the trained model data necessary for object detection.
|
||||
- `--source_video_path` (optional): The path to the source video file that will be
|
||||
analyzed. This is the input video on which crowd analysis will be performed.
|
||||
If not specified default is `people-walking.mp4` from supervision assets
|
||||
- `--target_video_path` (optional): The path to save the output.mp4 video with annotations.
|
||||
- `--confidence_threshold` (optional): Sets the confidence threshold for the YOLO model
|
||||
to filter detections. Default is `0.3`. This determines how confident the model should
|
||||
be to recognize an object in the video.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model. Default is 0.7. This value is used to manage object detection accuracy,
|
||||
particularly in distinguishing between different objects.
|
||||
- `--heatmap_alpha` (optional): Opacity of the overlay mask, between 0 and 1.
|
||||
- `--radius` (optional): Radius of the heat circle.
|
||||
- `--track_threshold` (optional): Detection confidence threshold for track activation.
|
||||
- `--track_seconds` (optional): Number of seconds to buffer when a track is lost.
|
||||
- `--match_threshold` (optional): Threshold for matching tracks with detections.
|
||||
|
||||
## ⚙️ run
|
||||
|
||||
```bash
|
||||
python script.py \
|
||||
--source_weights_path weight.pt \
|
||||
--source_video_path input_video.mp4 \
|
||||
--confidence_threshold 0.3 \
|
||||
--iou_threshold 0.5 \
|

## 🛠️ script arguments
|
||||
|
||||
- `--roboflow_api_key` (optional): The API key for Roboflow services. If not provided
|
||||
directly, the script tries to fetch it from the `ROBOFLOW_API_KEY` environment
|
||||
variable. Follow [this guide](https://docs.roboflow.com/api-reference/authentication#retrieve-an-api-key)
|
||||
to acquire your `API KEY`.
|
||||
- `--model_id` (optional): Designates the Roboflow model ID to be used. The default
|
||||
value is `"yolov8x-1280"`.
|
||||
|
||||
- `--source_weights_path`: Required. Specifies the path to the YOLO model's weights
|
||||
file, which is essential for the object detection process. This file contains the
|
||||
data that the model uses to identify objects in the video.
|
||||
- `--source_video_path`: Required. The path to the source video file that will be
|
||||
analyzed. This is the input video on which traffic flow analysis will be performed.
|
||||
- `--target_video_path`: The path to save the output video with
|
||||
annotations. If not specified, the processed video will be displayed in real-time
|
||||
without being saved.
|
||||
- `--confidence_threshold` (optional): Sets the confidence threshold for the YOLO
|
||||
model to filter detections. Default is `0.3`. This determines how confident the
|
||||
model should be to recognize an object in the video.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model. Default is 0.7. This value is used to manage object detection
|
||||
accuracy, particularly in distinguishing between different objects.

## 🛠️ script arguments
|
||||
|
||||
- ultralytics
|
||||
|
||||
- `--source_weights_path`: Required. Specifies the path to the YOLO model's weights
|
||||
file, which is essential for the object detection process. This file contains the data
|
||||
that the model uses to identify objects in the video.
|
||||
|
||||
- `--source_video_path`: Required. The path to the source video file to be processed.
|
||||
This is the video on which object detection and annotation will be performed.
|
||||
- `--target_video_path`: Required. The path where the processed video, with annotations
|
||||
added, will be saved. This is your output video file.
|
||||
- `--confidence_threshold` (optional): Sets the confidence level at which the model
|
||||
identifies objects in the video. Default is `0.3`. A higher threshold makes the model
|
||||
more selective, while a lower threshold makes it more inclusive in identifying objects.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model, defaulting to `0.7`. This parameter helps in differentiating between
|
||||
distinct objects, especially in crowded scenes.
|
||||
|
||||
- inference
|
||||
|
||||
- `--roboflow_api_key` (optional): The API key for Roboflow services. If not provided
|
||||
directly, the script tries to fetch it from the `ROBOFLOW_API_KEY` environment
|
||||
variable. Follow [this guide](https://docs.roboflow.com/api-reference/authentication#retrieve-an-api-key)
|
||||
to acquire your `API KEY`.
|
||||
- `--model_id` (optional): Designates the Roboflow model ID to be used. The default
|
||||
value is `"yolov8x-1280"`.
|
||||
|
||||
- `--source_video_path`: Required. The path to the source video file to be processed.
|
||||
This is the video on which object detection and annotation will be performed.
|
||||
- `--target_video_path`: Required. The path where the processed video, with annotations
|
||||
added, will be saved. This is your output video file.
|
||||
- `--confidence_threshold` (optional): Sets the confidence level at which the model
|
||||
identifies objects in the video. Default is `0.3`. A higher threshold makes the model
|
||||
more selective, while a lower threshold makes it more inclusive in identifying objects.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model, defaulting to `0.7`. This parameter helps in differentiating between
|
||||
distinct objects, especially in crowded scenes.

## 🛠️ script arguments
|
||||
|
||||
- ultralytics
|
||||
|
||||
- `--source_weights_path`: Required. Specifies the path to the YOLO model's weights
|
||||
file, which is essential for the object detection process. This file contains the
|
||||
data that the model uses to identify objects in the video.
|
||||
|
||||
- `--source_video_path`: Required. The path to the source video file that will be
|
||||
analyzed. This is the input video on which traffic flow analysis will be performed.
|
||||
- `--target_video_path` (optional): The path to save the output video with
|
||||
annotations. If not specified, the processed video will be displayed in real-time
|
||||
without being saved.
|
||||
- `--confidence_threshold` (optional): Sets the confidence threshold for the YOLO
|
||||
model to filter detections. Default is `0.3`. This determines how confident the
|
||||
model should be to recognize an object in the video.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model. Default is 0.7. This value is used to manage object detection
|
||||
accuracy, particularly in distinguishing between different objects.
|
||||
|
||||
- inference
|
||||
|
||||
- `--roboflow_api_key` (optional): The API key for Roboflow services. If not provided
|
||||
directly, the script tries to fetch it from the `ROBOFLOW_API_KEY` environment
|
||||
variable. Follow [this guide](https://docs.roboflow.com/api-reference/authentication#retrieve-an-api-key)
|
||||
to acquire your `API KEY`.
|
||||
- `--model_id` (optional): Designates the Roboflow model ID to be used. The default
|
||||
value is `"vehicle-count-in-drone-video/6"`.
|
||||
|
||||
- `--source_video_path`: Required. The path to the source video file that will be
|
||||
analyzed. This is the input video on which traffic flow analysis will be performed.
|
||||
- `--target_video_path` (optional): The path to save the output video with
|
||||
annotations. If not specified, the processed video will be displayed in real-time
|
||||
without being saved.
|
||||
- `--confidence_threshold` (optional): Sets the confidence threshold for the YOLO
|
||||
model to filter detections. Default is `0.3`. This determines how confident the
|
||||
model should be to recognize an object in the video.
|
||||
- `--iou_threshold` (optional): Specifies the IOU (Intersection Over Union) threshold
|
||||
for the model. Default is 0.7. This value is used to manage object detection
|
||||
accuracy, particularly in distinguishing between different objects.

In `sv.Detections`, detection data is categorized into two main field types:

fixed and custom. The fixed fields include `xyxy`, `mask`, `confidence`,

`class_id`, and `tracker_id`. For any additional data requirements, custom
|
||||
fields come into play, stored in the data field. These custom fields are easily
|
||||
accessible using the `detections[<FIELD_NAME>]` syntax, providing flexibility
|

for diverse data handling needs.
