Reference no: EM133627787

Question: Write a function, g = dftFiltering (f, H, padmode) to filter image f with a given filter transfer function H. Your function should implement the seven steps in the filtering algorithm discussed in class. If padmode = 'replicate', then replicate padding should be used. If padmode = 'zeros', zero padding should be used. (2) Read the image testpattern512.tif, filter it with a Butterworth lowpass filter with cutoff a frequency of 32 and order 2. Display the result. (3) Read the image testpattern1024.tif and lowpass filter it using a Gaussian filter, choose parameters so that the large letter "a" is barely readable, and the other letters are not.
