Image Processing in CUDA

Hi,

I am working on a project which needs image processing pixel by pixel, I mean select pixels of certain color from image and get it’s coordinates but I am unable to do it with the documentation.
I am loading my images using OpenCV as cv::Mat.

Please help me achieve this as I am new in GPGPU.

Regards,

Hi,
You can use cv::cuda::GpuMat to get fast cv processing on gpu with threshold function / inRange function ocv::cuda implementation (see https://answers.opencv.org/question/91579/opencv-cuda-method-that-works-like-inrange/),

Another option is using Nvidia Performance Primitives (NPP) , e.g. https://docs.nvidia.com/cuda/npp/group__image__threshold__operations.html

Best Regards
