Patent ID: 7620214

Claim:
A human eye detection method for detecting a human eye by determining whether an unverified candidate eye area is a true eye area based on a neighborhood region of the unverified candidate eye area, comprising the following steps: a) inputting an image into an information processing apparatus; b) analyzing the image and getting the unverified candidate eye area, in the information processing apparatus; c) determining, in the information processing apparatus, the neighborhood region based on the unverified candidate eye area, the neighborhood region being defined as rectangle, the center of which is the center of the unverified candidate eye area and the size of which is calculated from the size of the image; d) calculating, in the information processing apparatus, the neighborhood region's size, which is recorded as S; e) detecting, in the information processing apparatus, dark areas in the neighborhood region and counting the number of dark areas, which number is recorded as N; and f) determining, in the information processing apparatus, whether or not the unverified candidate eye area is a true eye area by comparing the ratio N/S to a predetermined threshold, wherein if the ratio N/S is smaller than said threshold, the unverified candidate eye area is determined to be a true eye area; else, the unverified candidate eye area is determined to be a false eye area.
