I am trying to cut an image that I have uploaded into a java written program into quarters, specifically a pyramid. Every pyramid level will have a corresponding image, for example given an input image of abc.pgm, you will generate output images abc1.pgm for pyramid level 1, and abc2.pgm for pyramid level2. Each level should be in a quarter size from the previous level. But I really don't understand how to do this... any information would be greatly appreciated!

okay, so after going back over the question for the homework I found out that what my professor really meant was image pyramid! "pyramid representation by smoothing and
down-sampling with a scaling ratio of 2" ...or I think that is what she meant. Correct me if I am wrong.
