Operators For Facial Feature Extraction

Abstract

The extraction of human facial features from images in binary form has been shown to be useful in at least two areas of low data-rate image coding. One is in the transmission of moving cartoons over the public switched telephone network [1]-[3]. Another is in model-based coding, where analysis of the camera signal is needed to line up the software model with the exterior world [4]. Binarization of the input image is also used as a first stage in machine recognition of faces [5].
