与常见的肤色分割方法不同

该算法不需对肤色建模

不对彩色图像进行非线性彩色空间变换

而是直接将彩色原图变换到特征空间

在特征空间中定位平均脸特征数据的最佳匹配点.本文最后将该算法应用于复杂光源彩色图像的人脸检测中

实验结果验证了算法的有效性和鲁棒性

具有明显的应用价值.

Abstract

A new feature space transformation algorithm in color image is presented.Basing on high dimensional imaginal geometry and biomimetics informatics and taking advantage of variations in color information

this new algorithm transforms the color image into feature space and rectifies each feature value within its neighborhood.By using this method

image feature without the effect of different light conditions can be obtained.In face detection application

unlike traditional skin tune detection method

the new method directly transforms the color image into feature space and locates the face position in feature space by face template feature matching.In this paper

the application of this new method to face detection in complex light color images has also been discussed.According to experimental result

it can be seen that the proposed method is very efficient and has significant value in application.
