Abstract
Grouplet-based reversible encoding in transform domain is done in this chapter. Dihedral group is used for the purpose. Construction basics of G-Let for forward and inverse computation are discussed. Construction of G-Let D3 to D10 based on rotation and reflection operations is done extensively. Reversibility computation of G-Let D3 to D10 is also given in detail. Implementation of G-Let for all D3 to D10 for reversibility computation is shown in images with all G-Let components. Implementation of an algorithm for embedding and extraction with a payload of 0.5 bpB is given. Applications are given at end.
