Median FIlter with NPP How to? :S

Hello!

I would like to apply a 5x5 median filter to an image. I’m using the boxfilter demo that comes with the SDK, but I cannot find a function for the emdian filter, just for Min and max filters. Is the median filter implemented within NPP? if the answer is no, does anybody knows a CUDA accelerated 5x5 median filter implementation. All I want to do is compare a CUDA filter performance against an FPGA implementation that I’ve done.
Help please! External Image
