Paper Abstract

In this paper, we present a novel wavelet image coding method based on the concept of directional dilation. We investigate the relationship among coefficients within and cross subbands and find that the concept of directional dilation is very helpful in expressing positions of significant coefficients. Furthermore, we try to combine two efficient ways: in-band directional dilation and quad-tree prediction together. According to this, we designed a new wavelet encoder, and experiment results show that the proposed method can outperform many famous algorithms in literature yet still possesses the embedded property.
