Run the getModels.sh file from command line to download the needed model files

sudo chmod a+x getModels.sh
./getModels.sh

How to run the code

Command line usage for object detection using YOLOv3

  • Python

    • Using CPU

      • A single image:
      python3 object_detection_yolo.py --image=bird.jpg --device 'cpu'
      • A video file:
      python3 object_detection_yolo.py --video=run.mp4 --device 'cpu'
    • Using GPU

      • A single image:
      python3 object_detection_yolo.py --image=bird.jpg --device 'gpu'
      • A video file:
      python3 object_detection_yolo.py --video=run.mp4 --device 'gpu'
  • C++:

    • Using CPU

      • A single image:
      ./build/object_detection_yolo --image=bird.jpg --device=cpu
      • A video file:
       ./build/object_detection_yolo --video=run.mp4 --device=cpu
    • Using GPU

      • A single image:
      ./build/object_detection_yolo --image=bird.jpg --device=gpu
      • A video file:
       ./build/object_detection_yolo --video=run.mp4 --device=gpu

Compilation examples

  • Using g++
g++ -ggdb pkg-config --cflags --libs /usr/local/Cellar/opencv3/3.4.2/lib/pkgconfig/opencv.pc object_detection_yolo.cpp -o object_detection_yolo.out
  • Using CMake

    • On Unix systems
    mkdir build && cd build
    cmake ..
    cmake --build . --config Release
    cd ..
    • On Windows systems
    mkdir build
    cd build
    cmake -G "Visual Studio 16 2019" ..
    cmake --build . --config Release
    cd ..

Note: To run on Windows system, change syntax accordingly:

.\build\Release\object_detection_yolo --video=run.mp4 --device=gpu
