What is this?

Canny edge detection implemented in CUDA C/C++. Supports images and video. OpenCV is used for loading and writing media. Compiled for CUDA compute capability 8.9 (compute_89, sm_89) and tested on RTX 4060.

Comparison with an example from the article:

Configure

• headless - true for just writing output files, false for GUI
• media - image or video
• in - input path
• lowThreshold, highThreshold - percentages for retaining or discarding edges based on pixel values

Compile

nvcc -arch=sm_89 -O3 -o canny *.cu `pkg-config --cflags --libs opencv4`
