允许姿态变化的快速人脸特征检测
摘 要
本文提出一种在允许姿态显著变化的人脸图象上快速检测眼睛和嘴角的方法。该方法仅仅合理地假设人脸图象要以通过值分割将头发和眼睛与脸部明显分开。首先采用Hough变换并利用有脸的相似性和对称性约束确定两个瞳孔的位置，然后根据人体测量关系初略估计嘴部区域，最事利用积分投影方法得到嘴角的精确位置。

The Method of Threshold and Peak Detection Based on Histogram Exponent Smoothing
() Abstract
On the basis of image gray value histogram processing by using exponent smoothing,the paper proposed an auto detection algorithm of thresholds and peaks in histogram.Experimental results show that simple algorithm,greater running speed and reasonable thresholds and peaks can be obtained with this method.
