1. Type in the command

>> help imdemos

This will give you a list of sample TIFF images which come with the Image Processing Toolbox.

Make a list of ten sample images, and for each image

(a) determine its type (binary, greyscale, true colour or indexed colour),

(b) determine its size (in pixels)

(c) give a brief description of the picture (what it looks like; what it seems to be a picture of)

2. Pick a greyscale image, say cameraman.tif or some other. Using the imwrite function, write it to les of type JPEG, PNG and BMP. What are the sizes of those les?
3. Repeat the above question with (a) a binary image, (b) an indexed colour image, (c) a true colour image.
4. Take some indexed images, convert it to gray image and display the result, convert it to integer data type and display the result. compare the two images in terms of apperarance and pixel values and describe your understanding.
