Merge pull request #25794 from Abdurrahheem:ash/yolov10-support
Add sample support of YOLOv9 and YOLOv10 in OpenCV #25794 This PR adds sample support of [`YOLOv9`](https://github.com/WongKinYiu/yolov9) and [`YOLOv10`](https://github.com/THU-MIG/yolov10/tree/main)) in OpenCV. Models for this test are located in this [PR](https://github.com/opencv/opencv_extra/pull/1186). **Running YOLOv10 using OpenCV.** 1. In oder to run `YOLOv10` one needs to cut off postporcessing with dynamic shapes from torch and then convert it to ONNX. If someone is looking for ready solution, there is [this forked branch](https://github.com/Abdurrahheem/yolov10/tree/ash/opencv-export) from official YOLOv10. Particularty follow this proceduce. ```bash git clone git@github.com:Abdurrahheem/yolov10.git conda create -n yolov10 python=3.9 conda activate yolov10 pip install -r requirements.txt python export_opencv.py --model=<model-name> --imgsz=<input-img-size> ``` By default `model="yolov10s"` and `imgsz=(480,640)`. This will generate file `yolov10s.onnx`, which can be use for inference in OpenCV 2. For inference part on OpenCV. one can use `yolo_detector.cpp` [sample](https://github.com/opencv/opencv/blob/4.x/samples/dnn/yolo_detector.cpp). If you have followed above exporting procedure, then you can use following command to run the model. ``` bash build opencv from source cd build ./bin/example_dnn_yolo_detector --model=<path-to-yolov10s.onnx-file> --yolo=yolov10 --width=640 --height=480 --input=<path-to-image> --scale=0.003921568627 --padvalue=114 ``` If you do not specify `--input` argument, OpenCV will grab first camera that is avaliable on your platform. For more deatils on how to run the `yolo_detector.cpp` file see this [guide](https://docs.opencv.org/4.x/da/d9d/tutorial_dnn_yolo.html#autotoc_md443) **Running YOLOv9 using OpenCV** 1. Export model following [official guide](https://github.com/WongKinYiu/yolov9)of the YOLOv9 repository. Particularly you can do following for converting. ```bash git clone https://github.com/WongKinYiu/yolov9.git cd yolov9 conda create -n yolov9 python=3.9 conda activate yolov9 pip install -r requirements.txt wget https://github.com/WongKinYiu/yolov9/releases/download/v0.1/yolov9-t-converted.pt python export.py --weights=./yolov9-t-converted.pt --include=onnx --img-size=(480,640) ``` This will generate <yolov9-t-converted.onnx> file. 2. Inference on OpenCV. ```bash build opencv from source cd build ./bin/example_dnn_yolo_detector --model=<path-to-yolov9-t-converted.onnx> --yolo=yolov9 --width=640 --height=480 --scale=0.003921568627 --padvalue=114 --path=<path-to-image> ``` ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake

#### Exporting YOLOv10 model
|

|

In oder to run YOLOv10 one needs to cut off postporcessing with dynamic shapes from torch and then convert it to ONNX. If someone is looking for on how to cut off the postprocessing, there is this [forked branch](https://github.com/Abdurrahheem/yolov10/tree/ash/opencv-export) from official YOLOv10. The forked branch cuts of the postprocessing by [returning output](https://github.com/Abdurrahheem/yolov10/blob/4fdaafd912c8891642bfbe85751ea66ec20f05ad/ultralytics/nn/modules/head.py#L522) of the model before postprocessing procedure itself. To convert torch model to ONNX follow this proceduce.

||||

||||
@code{.bash}
|
||||
git clone git@github.com:Abdurrahheem/yolov10.git

conda create -n yolov10 python=3.9

conda activate yolov10

python export_opencv.py --model=<model-name> --imgsz=<input-img-size>

By default `--model="yolov10s"` and `--imgsz=(480,640)`. This will generate file `yolov10s.onnx`, which can be use for inference in OpenCV

|
||||
- --classes: File path to a text file containing class names for object detection.
|
||||
- --thr: Confidence threshold for detection (e.g., 0.5).
|
||||
- --nms: Non-maximum suppression threshold (e.g., 0.4).
|
||||
- --mean: Mean normalization value (e.g., 0.0 for no mean normalization).
|
||||
- --scale: Scale factor for input normalization (e.g., 1.0).
|

- --scale: Scale factor for input normalization (e.g., 1.0, 1/255.0, etc).
|

- --yolo: YOLO model version (e.g., YOLOv3, YOLOv4, etc.).
|
||||
- --padvalue: Padding value used in pre-processing (e.g., 114.0).
|
||||
- --paddingmode: Method for handling image resizing and padding. Options: 0 (resize without extra processing), 1 (crop after resize), 2 (resize with aspect ratio preservation).
|
||||
- --backend: Selection of computation backend (0 for automatic, 1 for Halide, 2 for OpenVINO, etc.).
|
||||
- --target: Selection of target computation device (0 for CPU, 1 for OpenCL, etc.).
|
||||
- --device: Camera device number (0 for default camera). If `--input` is not provided camera with index 0 will used by default.
|

- --width: Model input width. Not to be confused with the image width. (e.g., 416, 480, 640, 1280, etc).
