EDGE DETECTION OF HUMAN EYE BASED ON HOMOGENEITY ANALYSIS

[摘要] Edge detection of eye is a pre-requisite stage for many applications such as iris recognition fatigue detection based on eye-blink count and eye-directed instruction control. This paper presents a method using image processing techniques to detect the edge of eyes in an image. Experiment result is presented and discussed at the end of this paper. Only gray levels are considered for the proposed method. The algorithms for edge detection of eye were assessed on 102 images from the Purdue database and on 897 images from a video sequence.
