This is the latest version of this item.
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.
