The list of supported platforms is shown below:\n\n| Target                             |  Support  |   Notes                     |\n|------------------------------------|:---------:|:---------------------------:|\n| GPU Coder                          |     ✔     |    run `gpuCodegenYOLOv9.m` |\n| MATLAB Coder                       |     ✔     |    run `codegenYOLOv9.m`    |\n\nTo deploy YOLO v9 to GPU Coder, run `gpuCodegenYOLOv9.m`. This script calls the `yolov9Predict.m` entry point function and generate CUDA code for it. It will run the generated MEX and give an output.\nFor more information about codegen, see [Deep Learning with GPU Coder](https://in.mathworks.com/help/gpucoder/gpucoder-deep-learning.html).\n\n## Simulink\nSimulink is a block diagram environment used to design systems with multidomain models, simulate before moving to hardware, and deploy without writing code. For more information about Simulink, see [Get Started with Simulink](https://in.mathworks.com/help/simulink/getting-started-with-simulink.html)\n\n```matlab\n% Read test image.\nI = imread(fullfile('data/Input','inputTeam.jpg'));\n\n% Open Simulink model.\nopen('yolov9SimulinkSupport.slx')\n```\nTo run the simulation, click `Run` from the `Simulation` tab.\n\nThe output will be logged to the workspace variable `out` from the Simulink model.\n\n## Network Overview\nYOLO v9 is one of the best performing object detectors and is considered as an improvement to the existing YOLO variants such as YOLO v5, YOLOX and YOLO v8.\n\nFollowing are the key features of the YOLO v9 object detector compared to its predecessors:\n- Improved Accuracy: YOLO v9 is expected to offer enhanced accuracy in object detection compared to its previous versions. This improvement can lead to more precise and reliable detection results.\n- Better Speed and Efficiency: YOLO v9 may have optimizations that allow it to achieve faster processing speeds while maintaining high accuracy. This can be crucial for real-time applications or scenarios with limited computational resources.\n- Enhanced Object Classification: YOLO v9 may introduce improvements in object classification capabilities, allowing for more accurate and detailed classification of detected objects. \n\n\n## References\n[1] https://github.com/ultralytics/ultralytics\n\n[2] Lin, T., et al. \"Microsoft COCO: Common objects in context. arXiv 2014.\" arXiv preprint arXiv:1405.0312 (2014).\n\n\nCopyright 2024 The MathWorks, Inc.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmatlab-deep-learning%2FPretrained-Yolov9-Network-For-Object-Detection","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmatlab-deep-learning%2FPretrained-Yolov9-Network-For-Object-Detection","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmatlab-deep-learning%2FPretrained-Yolov9-Network-For-Object-Detection/lists"}
