thank you sir for your answers

Hi,

Can be used because those are specifics quantitative measures of "X" with the capability of describe classes.

Arturo Tozzi

Through the concept of entropy, you are able to know the macroscopic features of a system (in your case the breast thermogram) without a knowledge of the microscopic features.
