Power functions and their use in selecting distance functions for document degradation model validation

摘要: Two document degradation models that model the perturbations introduced during printing and scanning process were proposed recently. Although are very useful, it is important we validate these by comparing synthetically generated images against real images. In recent past, two different validation procedures have also been to such models. These functions of sample size various distance functions. this paper outline a statistical methodology compare schemes result using This general enough any schemes.
