yolov4-opencv-cpp-python

Example of using YOLO v4 with OpenCV, C++ and Python

Prerequisites

Make sure you have already on your system:

• OpenCV 4.0+
• Python 3.7+
• Any modern Linux OS (tested on Ubuntu 20.04)
• GCC 9.0+

Running the python script

The python code is here.

git clone https://github.com/doleron/yolov4-opencv-cpp-python.git
cd yolov4-opencv-cpp-python
python python/yolo.py 

If you machine/OpenCV install are CUDA capable you can try out running using the GPU:

git clone https://github.com/doleron/yolov4-opencv-cpp-python.git
cd yolov4-opencv-cpp-python
python python/yolo.py cuda

Running the C++ program

The C++ code is here.

git clone https://github.com/doleron/yolov4-opencv-cpp-python.git
cd yolov4-opencv-cpp-python
g++ -O2 cpp/yolo.cpp -o yolo_example `pkg-config --cflags --libs opencv4`
./yolo_example

Or using CUDA if available:

git clone https://github.com/doleron/yolov4-opencv-cpp-python.git
cd yolov4-opencv-cpp-python
g++ -O2 cpp/yolo.cpp -o yolo_example `pkg-config --cflags --libs opencv4`
./yolo_example cuda
