no, you can't access pixels on the gpu (same for GpuMat or UMat) , only on the cpu.

either: find out, if there's something doing what you want in the gpu api already, and use that (chances are high, that you only missed it !)

or: download it from the gpu, do your processing, upload again (expensive)
