1. A human eye detecting method for detecting human eye in an image, comprising:
- a reading step of reading the gray level of each pixel in the each column in the image;
a segmenting step of segmenting each column into a plurality of intervals, and labeling each of the intervals as valley region, intermediate region or peak region;
a merging step of merging the valley region of the each column and the valley region of its adjacent column, and generating an eye candidate region; and
a determining step of determining the human eye from the eye candidate regions.

Abstract
Disclosed is a method, apparatus, and system for detecting a human face in an image. The method includes, for a subset of pixels in the image, deriving a first variable from the gray-level distribution of the image and deriving a second variable from a preset reference distribution that is characteristic of the object. The method further includes evaluating the correspondence between the first variable and the second variable over the subset of pixels and determining if the image contains the object based on the result of this evaluation.
