Redefine Median Filter in Matlab [closed] Ask Question Asked 2 years, 3 months ago. Active 2 years, 3 months ago. Viewed 56 times 1 $\begingroup$ Closed. This question is off-topic.

The main idea of the median filter is to run through the signal entry by entry, replacing each entry with the median of neighboring entries. Median filtering is a nonlinear operation often used in image processing to reduce "salt and pepper" noise. A median filter is more effective than convolution when the goal is to simultaneously reduce noise and preserve edges. For information about performance considerations, see ordfilt2.

Zmin = minimum gray level value in Sxy. The Median Filter block computes the moving median of the input signal along each channel independently over time. The block uses the sliding window method to compute the moving median. In this method, a window of specified length moves over each channel sample by sample, and the block computes the median of the data in the window. In terms of your speed query, I'd propose that your pseudomedian filter is faster because it doesn't involve sorting.

Median filtering is a nonlinear operation often used in image processing to reduce "salt and pepper" noise. A median filter is more effective than convolution when the goal is to simultaneously reduce noise and preserve edges. For information about performance considerations, see ordfilt2. The dsp.MedianFilter System object™ computes the moving median of the input signal along each channel, independently over time. The object uses the sliding window method to compute the moving median. y = medfilt1 (x) applies a third-order one-dimensional median filter to the input vector, x . The function considers the signal to be 0 beyond the endpoints.

If you type in median there, you'll see that you can use medfilt2() in the Image Processing Toolbox. I have a demo that uses medfilt2() to remove salt and pepper noise in RGB images, if you want to see it.
