Opencv adaptive median filter
WebMedian filtering is a nonlinear operation often used in image processing to reduce "salt and pepper" noise. A median filter is more effective than convolution when the goal is to simultaneously reduce noise and preserve edges.

Web8 de jan. de 2013 · OpenCV provides four main types of blurring techniques. 1. Averaging This is done by convolving an image with a normalized box filter. It simply takes the average of all the pixels under the kernel area and replaces the central element. This is done by the function cv.blur () or cv.boxFilter (). Check the docs for more details about the kernel.
