Detailed Description

Determines absolute difference between each pixel of an image and a constant value.

Note: If you use one of the device constant versions of these functions and the function called immediately preceeding that function generates that device constant you MUST either call cudaStreamSynchronize() or cudaDeviceSynchronize() before calling the device constant function.
