Wavelet-Based Image Compression
16.1 Overview
In this chapter we examine the implementations of several wavelet-based image compression schemes. We begin with the earliest, the embedded zerotree wavelet coder, and then look at an image coder based on set partitioning, and finally, we look at JPEG2000—the latest image compression standard.
16.2 Introduction
One of the most popular applications of wavelets has been image compression. The JPEG 2000 standard, which is increasingly becoming the compression method of choice for a wide range of applications from compression of movies to compression of medical images, uses wavelets instead of the discrete cosine transform (DCT) to perform decomposition of the image. During our discussion, we have always ...
