To observe several applications of image processing in MATLAB, load your own photo to

MATLAB enviroment and save it to any variable. Can you say that how does MATLAB store your photo?

Using 'size' command, print the number of pixels of your photo to command window. Observe the

resulting numbers. By looking at the size of any photo, can you interpret the shooting quality? If so$,$

how?

Display your photo in MATLAB. Then use $\text{'}$rgb$2$grey' command and display it again. What does MATLAB

do by $\text{'}$rgb$2$grey' command? Explain in detail. And do laplacian and gaussian filter too.
