Image Compression: A Study of the Iterated Transform Method

Abstract

This paper presents results from an image compression scheme based on iterated transforms. Results are examined as a function of several encoding parameters including maximum allowed scale factor, number of domains, resolution of scale and offset values, minimum range size, and target fidelity. The performance of the algorithm, evaluated by means of fidelity versus the amount of compression, is compared with an adaptive discrete cosine transform image compression method over a wide range of compressions.
