Paper Abstract

With the continuing growth of modern communication technologies, the demand for image transmission is increasing rapidly. Transmitting a high resolution images over low bandwidth communication lines usually requires a great amount of time and the user interaction with such a transiiission eiivitonment can become frustrating. The problem can be eased somewhat by transmitting a SelICS of lOW resolution approximations which outlines the final image. Progressive image transmission is being applied in interactive image comiriunications tlia.t tia usmit )VCr low bandwidth channels. The progressive build-up is a way of reordering the coded data 1)IiOI transmission, so that a rough approximation will appear first and l)C followed by SuCCeSSively 11101-C detailed versions of the final image. In this paper, we investigate the objective fidelity for several widely used progressive graylevel i i-n age transmission algorithms which include both time and frequency-domain appiOa dies, and also propose some efficient implementations to improve their performance without increasing (Ufli Putational complexity.
