An analysis of isometry transforms in frequency domain for fast fractal encoding

A new fast fractal encoding algorithm, which minimizes the iterations of isometry transforms for each domain block, is proposed. The effects of isometry transforms are analyzed in the Walsh-Hadamard transform (WHT) domain, and the search for the minimum Euclidean-distance isometry transform to a ran...
