用hough和最小二乘法实现虹膜的定位,用matlab实现,非常成功的例子-Hough and least squares method used to achieve the positioning of the iris, using matlab to achieve very successful examples of

提出了一种针对复杂环境下的过人脸检测方法，首先在CbCgCr空间利用直接最小二乘法构建了对光照和复杂背景鲁棒性更好肤色聚类模型，实现了准确的肤色检测；然后针对人脸中姿态和表情变化，提出了基于Adaboost的多姿态人脸检测，精确的实现了人脸检测定位。-Extraordinary face detection method for complex environments, the first space CbCgCr ​ ​ direct least squares meth
