<title>New image-compression algorithm using wavelet analysis</title>

Abstract

The conventional approach of using DCT (discrete cosine transform) which is Fourier based has been most popular in industry. The advantages and potentials of image compression using wavelet analysis are now being explored. In this paper a new image compression algorithm based on wavelet analysis is presented that makes use of a lifting scheme and a modification of the 3-D subband coding. The exploitation of contexts in both space-time and space-space brings out an improved algorithm that is both performance effective and computationally efficient. The software system using this algorithm has the advantage that it is much more flexible and less costly than hardware systems. The new algorithm has been tested with the compression oftraffic scene video with satisfactory results.
