Median Filter – Edge Preserving Filter Tutorial

The Median filter is a nonlinear noise reduction technique that is widely used in image processing. It is very effective in cases of salt and paper noise (impulsive noise) and speckle noise. However, in cases…

Mean Filter: Box blur for fast noise reduction

The Mean filter is a linear low-pass blur photo filter where each pixel in the output image has average value of its neighboring pixels. The algorithm is also famous as Box blur and performs as…
