METHOD FOR DETECTING EYES FROM FACE IMAGE BY OPTIMUM BINARY THRESHOLD SEARCH

摘要

PURPOSE: A method for detecting eyes from a face image by an optimum binary threshold search is provided to increase the adaptability of an input gray level face image to an illuminating state and maximize the performance of eye detection. CONSTITUTION: A gray level face image is inputted to a computer(S100). A threshold is generated according to a threshold search direction for making the input gray level face image binary(S200). An eye pair is detected from the black and white face image(S300). If eye pair information is output, the eye pair is finally output as eyes detected from the input gray level face image(S500). If the eye pair detection fails, the threshold search direction is decided to execute threshold generation and binary process again(S400).
