WebFilter Data Filter Difference Equation. Filters are data processing techniques that can smooth out high-frequency fluctuations in data or remove periodic trends of a specific frequency from data. In MATLAB ®, the filter function filters a vector of data x according to the following difference equation, which describes a tapped delay-line filter. WebFilter the image using bilateral filtering. Set the degree of smoothing to be larger than the variance of the noise. DoS = 2*patchVar; J = imbilatfilt (I,DoS); imshow (J) title ( [ 'Degree of Smoothing: ' ,num2str (DoS)]) The striation artifact is reduced, but not eliminated. To improve the smoothing, increase the value of spatialSigma to 2 so ...
