WebThe median filter is a nonlinear digital filtering technique, often used to remove noise. Such noise reduction is a typical pre-processing step to improve the results of later processing. The Wiener filter is the MSE (mean squared error) optimal stationary linearfilter for images degraded by additive noise and blurring.

WebThe "MedianFilter" operation is a non-linear filter which is useful for removing isolated lines or pixels while preserving the overall appearance of an image. The filter is implemented by moving a mask over the image. For each position of the mask, the center pixel is replaced by the median of the pixel values covered by the mask. importance of socrates philosophyWebAbstract –In the field of image processing, image restoration is the most essential task.
