Next: A New Entropy Measure Based on Multiple Resolution and Noise Modeling . ... The entropy measurement has been proposed for image restoration several years ago in astronomy. ... The multiscale entropy has the advantage to introduce a noise modeling, and the concept of information at different level of resolution. ... We show in this paper that it can also be used for background fluctuations analysis. ... Five simulated images were created by adding 400, 200, 100, 50, 0 sources to a noisy image. ...
