According to the DFT property of Laplacian, it appears we may implement Laplacian operation by designing a digital filter with frequency response H(u,v) = K(u2+v2) where K is a scaling factor to make the magnitude of H(u,v) in the range [0, 1]. Use this frequency- domain scheme to find the Laplacian image for the bird image.
Your report (Word or pdf format) should contain:
- Source codes
- Figures of the Fourier magnitude spectra of the bird image after applying Laplacian filtering
- Figure of the Fourier magnitude of Laplacian filter H(u,v)
- Figure of the output image
- Table of top 25 DFT frequencies (u,v) after Laplacian filtering
