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, seeordfilt2. ...

Copy Code Copy Command Generate a sinusoidal signal sampled for 1 second at 100 Hz. Add a higher-frequency sinusoid to simulate noise. Get fs = 100; t = 0:1/fs:1; x = sin(2*pi*t*3)+0.25*sin(2*pi*t*40); Use a 10th-order median filter to smooth the signal. Plot the res...

A median filter in images works the same way, only in 2D. So you take not only the values (pixels) that are left or right, but all the values that surround the sample (pixel) you are in. In MATLAB, check medfilt1 and medfilt2 ;) . ThemeCopy doc medfilt1; doc medfilt2; Anywa...
median filter in matlab and also in matlab simulink. i tried to convert the matlab code to HDL code with HDL coder. but i found alwais this error ''Found unsupported dynamic matrix type at output port: 0, name 'im_med', in the file/function MedFiltre_fixpt " .someone can help me ...
One of the most widespread techniques in demosaiced image postprocessing is median filtering. Such a filter has been used for years to remove impulse noise in grey-level images, but it also efficiently removes color artifacts without damaging local color variations. Freeman (1988) was the first ...
