@sturkmen yes. Can you please explain what do they do to an image differently? In layman's term

Actually i am using blur operation to smoothen the image. Strangly gpu::blur is taking more time than c::blur hence i was planning to replace it with dilate. But couldnt exactly figure out their effect on same image.

i can't test gpu::blur but it must be faster than cv:blur Afaik. try gpu::GaussianBlur or gpu::sepFilter2D
