Assume we have a sensor field with dimension M*M. In order to apply any data compression technique, first I want to know what is the compression limit or minimum entropy of the entire sensor field. How could I compute the minimum entropy or compression limit for the sensor field?
Actually I want to have the theoretical compression limit. Let's put the problem for an image. I want to know whether there are any mathematical methods to calculate the theoretical compression limit. Please let me know or suggest any readings to formulate the problem.
