Are there libraries and tutorials on image processing on CUDA?

Process images in R (classification, mathematical operations on pixel values in different channels, etc.). For example, pixel-by-pixel subtracted from the pixel values of the IR channel values of the red channel - only one entry.

Studied CUDA, but very hard work with the calculations of the threads and memory allocation. Are there libraries to simplify these operations on CUDA?
