In fact there is one project named GpuCV (https://picoforge.int-evry.fr/cgi-bin/twiki/view/Gpucv/Web/WebHome) that might interrest you. Our goal is to port most OpenCV operators to GPU, originally we where using GLSL for that task but I am now working on a CUDA plugin for GpuCV to help CUDA developpers to port new operators.
GpuCV 's CUDA plugin might be first released within a month, but a beta version is available on request.
Feedbacks are more than welcome!
Here is a few features that the plugin includes:
automatique data transfert between CPU buffer, OpenGL texture/buffer and CUDA memory.
operators [beeing] ported: GEMM, Avg, Dilate, Erode, Smooth, Laplace, Sobel, Sum, Histogram…
benchmarking tools included.
and more to come…
