Frost filter for speckle noise reduction
Web1) Homogeneous Area Speckle Noise Reduction parameter data in Table 1, shows the highest ENL value achieved by the combination Frost-TMAV filter, it achieved in all difference areas, and this mean it has stronger ability to reduction the speckle noise. WebApr 4, 2015 · For some of those a median filter is a decent way to reduce noise, though maybe not in the best way. For salt and pepper noise, you can use a modified median filter where you don't filter the whole image, which can introduce blurring even with a median filter, but find the noise first and replace the noise ONLY with the median filtered value.
