Matlab tillhandahåller en metod för att skapa ett fördefinierat 2-D-filter. av J Antolin-Diaz · Citerat av 9 — Both suggest that a possible shift in the mean of US GDP growth exists, the latter Wang for providing the Matlab code for the square-root form Kalman Filter.

The object uses the sliding window method to compute the moving median. The median filter considers each pixel in the image in turn and looks at its nearby neighbors to decide whether or not it is representative of its surroundings. Instead of simply replacing the pixel value with the mean of neighboring pixel values, it replaces it with the median of those values. B(i-1,j-1)=median(K); Vectorized Method: The iterative method is little slow.

Median filtering is particularly useful for salt-and-pepper noise where it is highly probable that these noisy pixels will appear the beginning and at the end when sorting pixel neighbourhoods, so choosing the middle value will most likely filter out these noisy values.

det beräknar medelvärdet av alla pixlar i ett område runt aktuell Ett annat sätt att filtrera bort brus är det icke-linjära median-filtret. Virtually all filtering is a local neighbourhood operation. ○ Convolution = linear e.g. mean filter, Gaussian weighted filter (feel free to solve these in MATLAB).
