Adaptive joint subband vector quantisation codec for handheld videophone applications

Sheikh Akbari, A. and Soraghan, J.J. (2003) Adaptive joint subband vector quantisation codec for handheld videophone applications. Electronics Letters, 39 (14). pp. 1044-1046. ISSN 0013-5194 (http://dx.doi.org/10.1049/el:20030673)

Abstract

A new wavelet-based video codec is presented, which joins vectors in the same subbands of different frames in a frame group and uses the properties of the human visual system. Perceptual weights are designed and used in the vector selection and quantisation of the wavelet coefficients. Results indicate a significant improvement in frame quality compared to JPEG2000 image sequence coder.
