Eye and Lip Enhancement for Low-rate Videophony

Streit, J, Hanzo, L and Bradshaw, B (1996) Eye and Lip Enhancement for Low-rate Videophony At of PIMRC'96, Taiwan, Province of China. 15 - 18 Oct 1996. , pp. 1049-1053.

Record type: Conference or Workshop Item (Other)


A generic parametric coding enhancement for employment in very low-rate videophone systems is proposed in order to improve the subjectively important eye and lip representation. The four-step Algorithm 1 identifies the position of the eyes, nostrils, lips and nose using pre-processing and pattern-matching and after luminance adjustment and smoothing it overlays the best-matching entries from a trained codebook, if deemed beneficial in image quality terms. The benefits of the technique are demonstrated using the example of an 11.36 kbps fixed rate quad-tree codec.
