I and my group mates have a subject which is called modelling with private derivative differential equations. We are working on zooming and compressing of images. We must do this with differential equations. We will read information from the image and give it the differential equation as starting point on nodes. We know that these information must be numbers, but I have a question: "What type of numbers must be those? Integers? Doubles? Or what? Can you help me and tell me answer of this question or can you link me the issue where I will find this information?

From what you have written, it could be any of those depending on the specific images. What information are you given about the images? I think the only person who can answer that is the person who is giving you the images.

For example, I have an image and I want to compress it; I must save some information about image, and it must be numbers which will be given to the differential equation and what type should it be? Int or float?
