| 摘 要： | 针对复杂动态背景中的人脸检测问题，提出了一种基于差影运算和肤色识别的检测算法。该算法首先通过改进的差影运算初步确定人脸区域，然后建立一个人脸肤色模型进一步进行肤色匹配．从而实现由粗到细的人脸检测。实验证明，该算法可以适应不同的光照环境，不受人脸大小和朝向的限制。其运算速度和精度均达到实用要求。

| Abstract: | Face detection remains a challenge due to several difficulties, such as sizes of different faces, changing lighting conditions and so on. This paper presents an algorithm to face detection based on complex and dynamic background. The method involves locating human face like regions by subtracting two adjacent pictures of a series and using skin color model to segment face. Experiment shows that this method, suitable for varying lighting conditions and different face sizes is not subjected to the limitation of the sizes of human face and its direction. Both calculation speed and precision are up to required practical application. |
