Q$3)$ given the following image

a$-$ Apply Sobel mask to find magnitude of gradient and its direction.

b$-$ Develop an algorithm to localize edge in the gradient image $($Hint: look at slide$\backslash$#$24$ in the lecture note$)$

c$-$ Find and localize edge by using Laplacian of Gaussian algorithm. d$-$ Comment on the results that you get in parts $\backslash (\backslash$mathbf$\{$b$\}\backslash )$ and $\backslash (\backslash$mathbf$\{$c$\}\backslash ).$
