Hallo, I need help. I would like to do a 2D circular high pass filter using the matlab function FSPECIAL('DISK', RADIUS) but, this function is a low pass filter really. How could I change from low to high pass filter using this function?. I tried to do this filter doing my own algorithm with a matrix and I got to do a rectangular filter easily but my problem was that I didn't know how to round the squares to get a circular filter. Could somebody help me. Thank you all very much. Regards. |
