This is outside my area of expertise, but it seems like gpu::equalizeHist in OpenCV may implement the desired functionality?
NPP does not implement a function like the one you ask for, but it does implement the necessary building blocks.
The CUDA SDK contains a histogram equalization example using NPP and we gave a tutorial at this year’s GTC on contast enhancing an image using NPP’s arithmetic functions and image statistics functions (Min/Max).
Hi, Do you have a link to that tutorial in GTC archives? I cannot find it.
