Question 2 I Ii Use The Fspecial Function In Matlab With The Log Option To Construct A 15x15 Isotropic Laplacian O 1 (47.48 KiB) Viewed 27 times

Question 2 (i) (ii) Use the fspecial function in MATLAB with the 'log' option to construct a 15x15 isotropic Laplacian of Gaussian kernel with o2. Name the resulting kernel H. Display a mesh plot of the negative H (i.e., -H). Using the conv2 function in MATLAB with the 'same' option, apply H to Figure3 and call the result F. Display the original image, the filtered image, and the filtered image thresholded at zero. Find and display the zero crossings of Fas a contour plot superimposed on the raw image of Figure3. Hint: use the function contour with level set parameter [00] and color 'k' or 'r'. (iii)
