- 2 a radio broadcast network ( rbn ) is modeled by a probabilistic graph g with unreliable nodes and perfect edges
2无线广播网络(简称rbn )可以用一个点不可靠而边可靠的概率图g来表示。 - There are three steps of the concrete process of the algorithm : initial localization , separating image and confirmation . firstly , single gaussian model is used to imitate skin - color distribution , meanwhile , skin probability images which is smoothly disposed using middle wave is calculated to attain the initial localization . secondly , in order to separate the latent face region , it uses multimodal information that includes the region growing 、 the hue and brightness 、 skin probability images etc . at last , it adopts the criterion of morphology analysis and face characteristic draw to confirm the latent region
算法的具体过程主要分为三个阶段:人脸初定位、人脸分割和人脸确认,首先采用高斯模型来模拟肤色分布并构造出肤色概率图进行人脸的初定位,并对肤色概率图采用中值滤波进行平滑处理,接着利用区域生长准则和融合色度、亮度以及肤色概率图等多源信息相结合的方法对图像进行分割,以达到分割出潜在脸区的目的,最后采用人脸整体形状的确认准则和人脸特征提取的确认准则相结合的方法对潜在脸区的最终确认。 - This paper presents a new face detection algorithm for color video images based on skin color and multimodal information fusion . first , this paper presents a new means for selecting skin samples ; and then comparing skin distribution in the eight color spaces and analyzing the adaptability for different skin patterns , poses a face initial orientation ' s method which uses the single gaussian model in the tsl color spaces , and calculates skin probability images ; afterwards comprehensive comparing three typical threshold value separating algorithms , put forwards a face separating method which bases on region growing and fuses multimodal informations ; final , raises a face confirming algorithm which fuses three shape features
