WebDescription. example. J = medfilt2 (I) performs median filtering of the image I in two dimensions. Each output pixel contains the median value in a 3-by-3 neighborhood around the corresponding pixel in the input image. J = medfilt2 (I,[m n]) performs median filtering, where each output pixel contains the median value in the m -by- n ... WebThe median filter is a non-linear digital filtering technique, often used to remove noise from an image or signal.
