A novel technique is introduced to locate and track the facial area in videophone-type sequences. The proposed method essentially consists of two components: (i) a color processing unit, and (ii) a knowledge-based shape and color analysis module. The

A color segmentation scheme is presented for use in an object-based video coding environment. The proposed technique employs the HSV (hue, saturation, value) color space to partition a video-phone type sequence into a facial area and a set of arbitra

A method to extract the facial area of videophone sequences is discussed. The proposed technique utilizes the distribution of skin colours in the colour space to obtain an initial segmentation followed by several successive post-processing operations

Spatial interpolation is an important technique that is often used to recover an image from its downsampled version, or to simply perform image expansion. Many conventional linear techniques exist, however, these often perform rather poorly in a subj
