| 摘 要： | 针对人脸识别的输入图像信息量高低不均的问题,提出了一种多参数图像择优的评分机制CPEF主要有三点贡献:第一点是提出了一种新颖的基于主动形状模型(ASM)定位的人脸水平旋转程度评估方法;第二点是采用递归的方式计算权重;第三点是提出了一组参数定量地描述了图像择优方法.过程如下:首先,计算图像质量;其次基于二分类器判断人眼是否处于睁开状态;然后以颜色直方图信息判定人是否处于张嘴状态;最后,综合水平旋转程度及其他参数,配合权重,给出评分.在FERET人脸库上的实验结果证明,CPEF有效地将人脸图像按照入主观感受做出排名,准确率高达92％.并且按得分高低排序采用Gabor配合SVM做人脸识别对比测试,对比实验证明,经CPEF处理后的图像在人脸识别中的准确率显著提升.

| Abstract: | This paper presents a novel mechanism named CPEF(Composite Parameters for Evaluating Face images) for selecting an image to conduct the best result for face recognition applications from an image sequence. Firstly, an method based on ASM positioning for the evaluation of image rotation is provided. Then a recursive scheme for parameters weighing is utilized. Finally, a composite parameter model is proposed to rate the appropriate degree of an image for face recognition. The experimental results show that the proposed method produces similar results to subjective evaluation and the accuracy is 92%. Furthermore, the effectiveness of this work is proved by face recognition applications using Gabor feature and SVM classifier. |
