Design options on the development of a new tree-based wavelet image coder

Abstract

A wide variety of wavelet-based image compression schemes have been reported in the literature. Every new encoder introduces different techniques that can be taken into account for designing a new image encoder. In this paper, we present several design options and optimizations that will be used along with the LTW algorithm. However, these optimizations can be applied to other image compression algorithms or implementations. They improve the LTW rate/distortion performance in about 0.4 dB without increasing its computational cost, showing the importance of selecting good design options during the development of a new image encoder. © Springer-Verlag Berlin Heidelberg 2003.
