- Interestingly , however , human skin color in southern africa is not uniform
不过，有趣的是，南非各族群的肤色并不一致。 - But a series of discoveries has led us to construct a new framework for understanding the evolutionary basis of variations in human skin color
但是，一连串的发现引导我们建构了一个新的认知架构，来了解人类肤色变异的演化基础。 - Human skin color has been proven to be an effective feature and widely used in face detection in resent years . however , color is not a physical phenomenon . it is a perceptual phenomenon that is related to the spectral characteristics of electromagnetic radiation in the visible wavelengths striking the retina
肤色是一种简单有效的特征，在人脸检测中得到广泛的关注和应用，但传统的基于统计的肤色检测方法不能克服光照、摄像机、肤色差异等因素的影响。 - A systematic summary of previous work has been given first . then this paper presents a novel multi - stage face detection algorithm , which makes a good use of human face pattern ' s valuable information in colour image sequences . the difficult detection task has been divided into four steps : the preprocessing , which is to gain skin colored regions with human skin color model ; the roughly detection and face region refining by elliptic curve fitting ; the fine detection with facial features " detection and location ; the face / non - face classification step based on pca and gaussian density estimation technique
本文对彩色序列图像中的人脸检测和跟踪技术进行了深入的研究，其具体内容为：对近年来的研究工作进行了系统的介绍；提出了一个由粗到细的多阶段的人脸检测算法，该算法充分利用了序列图像中人脸模式的各种有用信息，将复杂的检测工作分为了四个部分：肤色区域分割预处理，人脸粗检及利用椭圆拟和的人脸区域提炼，应用人脸基本特征检测和定位的人脸细检， pca结合高斯概率密度估计的人脸验证。
