2. Histogram transformation [6 marks, 2 marks for each] Download a medical image of your choice from the internet. If the image is color, convert it into gray-scale. Then, deteriorate the contrast and brightness of the image by shifting/shrinking the histogram using a Matlab function "imadjust". Make the image darker or brighter, and less contrast. See #9 in the lab tutorial and Matlab help for "imadjust Use Matlab for the following questions. To copy/paste a Matlab figure in your answer, click Edit/Copy figure in the Matlab figure window menu and paste it. Show all images with the same grayscale range (if you use imshow, its default range is 0-255). Insert a grayscale bar beside each image (click Insert/Colorbar in the menu) *Attach (or indicate) matlab codes or functions that you used. * Your result and answer could be different from other students, depending on the image you chose. (a) Show and compare the gray scale image and its histogram between the original and deteriorated images. What is the dynamic range of the deteriorated image? (b) Improve the brightness/contrast of the deteriorated image by histogram equalization. Show the image and histogranm (c) Discuss the differences between the original image and the image obtained in (b). Also, iscuss the differences of their histograms
