color distribution meaning in English
色分布
Examples
- Description methods that employ dominant colors use a small number of color ranges to construct an approximate representation of color distribution
使用支配色的描述法用少量的色彩范围构造色彩分布的近似表示。 - An image has a larger texture standard property means it looks more like a texture intuitively . we researched a lot of images and textures to decide to use the color distribution histogram to measure this property , and obtained a good result
根据对大量纹理的形态研究，利用视觉上可以明显界定为纹理的图像的特征分布特性，我们使用纹理的色彩分布直方图来定义这种度量，取得了很好的效果。 - 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。 - In the process of evaluating particle weight , in order to distinguish the different color features of the objects , the original algorithm ( evaluating through bhattacharyya distance ) was improved . only the color distribution of the foreground pixel in particle area after the background modeling is counted , therefore the accuracy and efficiency of target tracking are increased
在评价粒子权值时,为了较好的区分目标之间的颜色特征,对原有的用bhattacharyya距离评价的算法进行了改进,仅统计背景建模后粒子区域前景像素的颜色分布,从而提高了目标跟踪的精度和效率。
