Opencv adaptive median filter
WebAn adaptive median filter performs spatial processing to reduce noise in an image. The filter compares each pixel in the image to the surrounding pixels. If one of the pixel values differ significantly from the majority of the surrounding pixels, the pixel is treated as noise. Web11 de mar. de 2012 · Adaptive median filtering is a new type of filtering that selects the noisy candidates and applies the median value over them – vini Dec 14, 2011 at 12:14 Ok, I see that this adaptive is different from the sliding median filter. Thanks, I'm learning something too :-) By the way, there are some implementations on Matlab Central.
