Abstract
Most commonly occurring images f(x,y) are not smoothly differentiable functions of the variables x and y. Rather, these images display edges, localized sharp features, and other significant fine scale details or texture. Correct characterization and calibration of the lack of smoothness in such images is important in various image processing tasks. So-called Lipschitz spaces appear to be the appropriate mathematical framework for accommodating non smooth images. The L1 Lipschitz exponent ?? for the given image, where ~0Citation
