Task 1

(1)Input color image

(2)Gray scale

(3)FFT2 of the input image

(4)Mask

(5)Remove high frequency using mask

Because low frequencies are centerd in the FFT image so that by zeroing out the rest could remove the high frequencies.

(6)Remove high frequency using conv2 with Gaussian Mask

Task 2

(1)Sharpened image

Task 3

(1)Two input images

I extract the second channel (G channel) in the second image (Hamerschelag Hall) to replace the G channel in the first image

(2)Result ghost image

Task 4

(1)Input dark image

(2)Gray scale

(3)Histogram Equalized image
