METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR BLINK DETECTION IN MEDIA CONTENT

摘要

A method and an apparatus is provided for blink detection in digital images. The method comprises computing a first classification feature or set of features associated with an eye region of an image (410a). Local binary patterns (LBP) may be used in calculating the features. A first state vector associated with the eye region may be computed based on the first classification feature and a plurality of predetermined constants (412a). A state of the eye region may be determined based on a comparison of the computed first state vector with a predetermined threshold (414). A second set of features may be computed from a mirror image of the eye region (408, 410b, 412b). The state of the eye region is one of a plurality of blink states associated with the eye region (416, 418).
