An adaptive approach for texture enhancement based on a fractional differential operator with non-integer step and order
Design of a novel non-regular self-similar support region to exclude pixels with low correlation. Adoption of non-integral pixel steps to maximally exploit the inherently high degree of self-similarity in texture patterns. Introduction of a new adaptive fractional order selection mechanism to deal with complex texture patterns. Design of a non-regular fractional differential operator mask to perform image texture enhancement.
