Coding of facial image sequence based on a 3-D model of the head and motion detection

摘要: Abstract Recently a new type of coding method, called intelligent image coding, or more specifically model-based has attracted much attention as basis for future visual communication services. The can be constructed by preparing 3-D-shape model an object on both the transmitting and receiving sides, only information about movement changes in shape this model. This paper discusses relation to moving facial images from two major objectives: extraction motion input sequence synthesis with limited amount information. First, concept basic outline are introduced, then procedures processing mouth eyes discussed. On side, feature-extracted is obtained applying thresholding operation image, characteristic points which represent shapes detected it. 3-D modified according above results realistic reproduced assigning appropriate luminance chrominance A method estimating head also briefly Experimental demonstrate feasibility system based described paper.
