WebNotice that the result has negative values. To avoid negative values in the output image, convert the input image to uint8 before performing the filtering. Since the input to imfilter is of class uint8, the output also is of class uint8, and imfilter truncates negative values to 0. A = uint8 (magic (5)); imfilter (A,h) WebGuided image filtering performs edge-preserving smoothing on an image. It uses the content of a second image, called a guidance image, to influence the filtering. Reduce noise in an image while using a guidance image to … solve for x and y simultaneously

This example shows how to use the wiener2 function to apply a Wiener filter (a type of linear filter) to an image adaptively. The Wiener filter tailors itself to the local image variance. Where the variance is large, wiener2 performs little smoothing. Where the variance is small, wiener2 performs more smoothing.
