WebHow do I reduce the noise of an image in Python? The mean filter is used to blur an image in order to remove noise. It involves determining the mean of the pixel values within a n x n kernel. The pixel intensity of the center element is then replaced by the mean. This eliminates some of the noise in the image and smooths the edges of the image. Web8 de jan. de 2013 · In this demo, I added a 50% noise to our original image and applied median blurring. Check the result: median = cv.medianBlur (img,5) Result: image 4.
