| 摘 要： | 提出了一种改进人像检测的方法，即在静态灰度图像中对差分得到的图像应用投影斜率，来增强对背景的鲁棒性，同时提出了将K-L模型应用于彩色图像定位检测中并结合Agent计算模型来提高搜索的速度的方法，与现有的算法比较有更好的适应性和快捷的速度，对应用研究有一定的指导意义，并在人像自动门禁系统和人像屏幕保护系统中取得了很好的应用效果。

| Abstract: | Proposesed an improved method of face detection, in which the projection slope is applied onto the image achieved through difference in the static grey image so as to strengthen the robust of the background. At the same time it proposes to apply K L model in colored image location and detection, and to increase the searching speed with the combination of Agent computing model. It has better adaptbility and faster speed compared with the current algorithms. All in all, it provides a guidance in the application research and obtains a satisfactory application effect in the respects of both automatic face system in door guarding and face system in screen protection. |
