Abstract
The aim of this paper is to examine a set of wavelet functions
(wavelets) for implementation in a still image compression system and to
highlight the benefit of this transform relating to today's methods. The
paper discusses important features of wavelet transform in compression
of still images, including the extent to which the quality of image is
degraded by the process of wavelet compression and decompression. Image
quality is measured objectively, using peak signal-to-noise ratio or
picture quality scale, and subjectively, using perceived image quality.
The effects of different wavelet functions, image contents and
compression ratios are assessed. A comparison with a
discrete-cosine-transform-based compression system is given. Our results
provide a good reference for application developers to choose a good
wavelet compression system for their application
