Answer the following questions Submit a pdf copy of vour answers to vour dropbox folder (vou may resize the outputs to fit several images in one page) and save all codes on a subfolder Use Matlab to implement the following on 'bacteria.tif image 1- Filter the image using the following operators a- Sobel b- Roberts c- Prewitt d- 5x5 sobel mask 14-6 4-1 2 -8 12-8 2 12 8 e- Use canny edge detector as a reference and the absolute difference between canny and the other outputs to quantify the error. List the results in one table 2- Use Matlab to implement average and median filters using the following size templates a- 3x3 b- 5x5 c- 9x9 d- 9x1 followed by 1x9 Display the input and output images. Discuss your results 3- Repeat problem 1 and 2 for the "bonemarr.tif image after applying noise to it You may use the following command to add noise to the image file Im-imread( lena.tif) 1m1=imnoise(im,' gaussian",0,0.25) 1m2=imnoise(im, salt & pepper',0.35) Im3-imnoise im, 'speckle,0.06) Where iml, im2, im3 are the resulted noisy images. The first parameter is the original image, the second parameter is noise type the third and fourth are the mean and variance of the noise
