Image Coding Using the Self-Similarity ofWavelet High-Frequency Components

S.Selvarajan, N.D.Kodikara


In this paper a novel approach Self-Similar Wavelet High- Frequency Components coding (SWHFC) to compress an image is proposed, based on the self-similarity of wavelet high-frequency components. The self-similarity of wavelet transformed image is explored by using the multiresolution concept of weighted finite automata (WFA). This scheme combines the multiresolution concept of WFA and wavelet multiresolution concept by introducing a predicative coefficients along with the each weights of WFA. Objective of this is to predict wavelet coefficients across scales, as to reduce the number of wavelet coefficients to be coded and the corresponding information of those.
