Abstract

The present invention provides an ASM-based dynamic image frontal face reconstruction system and method. The system comprises a dynamic video face extraction module, a face image quality evaluation module, a face image illumination processing module and a frontal face synthesis module. The dynamic video face extraction module can obtain an actual area of a face more accurately and eliminates the interference of the class skin color pixels, and a high-quality face image sequence can be obtained by the face image quality evaluation module and the face image illumination processing module. An ASM is used to carry out the characteristic point positioning on the obtained high-quality face images, and a thin plate spline (TPS) is utilized to synthesize a final face image. The ASM-based dynamic image frontal face reconstruction system and method of the present invention can synthesize the frontal face image effectively, and has certain improvement for synthesizing the frontal face by the face images with micro-expression.

Description

technical field [0001] The present invention mainly relates to the technical field of image processing, in particular to an ASM-based dynamic image front face reconstruction system and method. Background technique [0002] With the popularization of computers and the emergence of smart devices, technology has an increasing influence on people. With the intensification of globalization, people's demand for identity verification is becoming stronger and stronger. There is a big gap between traditional personal identification codes, passwords, IC cards, security cards and other traditional identification technologies due to their unchanging operations and difficulty in remembering and the needs of the information age. Face recognition is a very popular topic in the field of biometric identification. It is a biometric identification technology that is expected to be widely used in social and economic activities and people's daily life after fingerprint identification. Face reco...
