Reversible Transform Encoding via Discrete Binomial Transformation

Abstract

Reversible transform encoding via discrete binomial transformation is given in this chapter. The forward and inverse transformation pair is given at beginning of the chapter. The computation of reversibility is done with 2 x 2 sub-image with complete numerical examples. Algorithm for embedding and authentication has been discussed in detail with citation of numerical examples. Complete implementation of an algorithm for embedding and extraction is given with a payload of 1.5 bpB along with discussions of implementation results. Applications are given at end.
