PROBLEM 3 We want to perform edge detection in the space domain for the image shown in figure 1.

1) Write code to detect the edges of the image using the horizontal Sobel mask

2) Write code to detect the edges of the image using a vertical Sobel mask

3) Add the images obtained in the previous questions.

4) Discuss the results obtained in the previous questions.

5) Write code to detect the edges of the image using Laplacian

6) From the results of the previous questions, compare between the gradient and Laplacian for edge detection
