Objective: Improve Matlab programming skills Description: This optional project is to make a passport photo from the pictures taken by your mobile phone or camera. The requirements are stated on the governments website:

Digital Image Head Size Template

-The top of the head, including the hair, to the bottom of the chin must be between 50% and 69% of the image's total height. The eye height (measured from the bottom of the image to the level of the eyes) should be between 56% and 69% of the image's height. - Image pixel dimensions must be in a square aspect ratio (meaning the height must be equal to the width). Minimum acceptable dimensions are 600 pixels (width) x 600 pixels (height). Maximum acceptable dimensions are 1200 pixels (width) x 1200 pixels (height).

Your program should take the following input parameters: 1. im the input image 2. headsize -- the top of the head, including the hair, to the bottom of the chin in a percentage of the images total height. (50% to 69%) 3. eyeheight the distance from the bottom of the image to the level of the eyes in a percentage of the images total height. (56% to 69%) 4. dim photo size in pixels. (600 to 1200)

The prototype of your matlab function:

photo = YourName_PassportPhoto(im, headsize, eyeheight, dim)

Implementation Step 1: Find the coordinates of the eyes. Rotate the image to level the head position Step 2: Find the coordinates of the chin and the top of the head. Step 3: Crop the image into the required head size ratio and eye height ratio. The head should be centered. Prompt an error message if the input image does not have enough pixels for cropping. No need to change the background of the input picture. Step 4: Resample the cropped image into required dimensions
