Abstract
A practical method for estimating the lossless image compression bound based on high-order conditional entropy analysis is proposed. This analysis can be performed within an ordinary image as opposed to dealing with an enormous training set. Its feasibility and reliability have been verified on a large group of images naturally acquired by various imaging sensors
