第09章 人脸的检测与定位
- 人脸的检测与定位(在预处理部分,采用了特别的增强人脸特征与脸部皮肤之间对比度的方法及局域取阈值二值化方法,改进了预处理的效果。在图像分割部分,实现了经典的分合算法,并且使用成组算法改进了分合的效果。在人脸匹配部分,实现了基于眼睛和嘴的几何模型匹配,并对评价函数的构造进行了研究。)-Face Detection and Location (pretreatment, using a special facial features enhanced facial skin and the contr

- LED字符分割和识别, 在此项目中我们主要完成了对拍摄到的6位LED数字进行分割和识别的课题。识别的数字范围在0~9。由于拍摄环境比较复杂,需要解决复杂背景下对LED字符的分割问题。我们利用了图像的色彩信息,先进行基于色彩的分割,然后对分割结果进行了固定阈值的二值化,并利用投影修正完成了对LED数码管图像的分割,并使用基于模板匹配的算法进行了识别,在匹配过程中对图像进行了尺寸归一化处理。最终得到了较好的识别效果,对10幅样图的识别率达到100%-LED character segmentat
