The median filter is a non-linear digital filtering technique, often used to remove noise from an image or signal. Such noise reduction is a typical pre-processing step to improve the results of later processing (for example, edge detection on an image). Median filtering is very widely used in digital image processing because, under certain conditions, it preserves edges while removing noise (but see the discussion below), also having applications in signal processing.

Figure 6 shows that the median filter is able to retain the edges of the image while removing salt-and-pepper noise. Unlike the mean and Gaussian filter, the median filter does not produce artifacts on a color image. The median filter will now be applied to a grayscale image. Web25 jan. 2024 · We can use max and min filter to process image data in spatial domain. Furthermore, they belong among order-statistic filters along with median filter. As for spatial domain filtering, our filter is basically a small window we place on top of our image. fiche afu rtuv
