ask 1: Install the following image from ELearning website: Write a Matlab code to do to the following: 1. Read the following retinal image (test.jpg) and extract the green band from it. 2. Apply 33 averaging filter into the extracted green band. 3. Apply all of the following Sobel operators on the smoothed green band. 4. Display the response of each filter in a separated figure. 5. Store the summation of all responses from all filter in a new image. 6. Store the maximum response from all filters in a new image. 7. Threshold the images in (5) and (6) to give the best results as in a manual image above.
