TEMPLATE-BASED FACE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a template-based face detection method that enables accurate face detection less sensitive to variations in illumination and facial expression, facial concealment, and the like in the detection of a face from video information.;SOLUTION: The template-based face detection method includes: producing average face data from a face database, wavelet-transforming the produced average face data, and removing a low frequency component sensitive to illumination out of high and low frequency components of the transformed face average data; producing a template with only horizontal and vertical components of the high frequency components; and retrieving an initial face position using the template when an image is input, linearly combining the template with a high frequency wavelet coefficient corresponding to the face position in the current frame, and detecting the face by using the template obtained by the linear combination as a template for the next frame.;COPYRIGHT: (C)2006,JPO&NCIPI
