For each problem, be sure to append Matlab code and image hardcopy.

General tip: See the recent in-class Matlab examples for useful techniques.

Problem 1

Create a mesh plot and an image display of the magnitude frequency response of the following convolution filters (use a 64x64 grid for the zero-padded image; display the zero frequency in the center of the image):

Discuss your findings, i.e., try to relate the known behavior of the convolution filter to the frequency response you observe.

Problem 2

Perform frequency-domain filtering on the "cameraman" image by applying the following filters:

Report the specific values you use for cutoff frequency (or bandwidth and center frequency of the bandpass filter).

Display the output images, and also display the filters as either a mesh plot or as an image.
