This is my assignment:

http://www.cse.yorku.ca/course/2011/...201/Q2/Q2.html

I have no idea what is an image value. I tired looking it up but there's no help.

All the codes are given. I just need to complete the two methods. (a constructor and the computation part).

So, how do you compute it?

Can someone guide me through this?

Thank you for your time.
