Abstract - Adaptive filtering is a wide area of. Affiliated to the University of Mumbai. adaptive filter design using matlab.
Adaptive Filter Design Using Matlab, If the model you created in Design an Adaptive Filter in Simulink is not open on your desktop you can open an equivalent model by typing. The filter compares each pixel in the image to the surrounding pixels. If one of the pixel values differ significantly from the majority of the surrounding pixels the pixel is treated as noise.
