为了对光线变化的图像进行顺利侵害,提出了一
种利用贝叶斯学习方法来进行视频图像分割的算法,印先在每个像素点处对不断变化的背景建模,同时计算每个像素点
处的颜色直方图,再用这些直方图来表示该像素点处特征向量的概率分布,然后用贝叶斯学习方法来进行判断,以确定在光线缓慢或者突然变化的时候,每个像素点是属于前景还是属于背景。-In order to change the image of light against a smooth, a Bayesian learning approach t

运动检测的目的是从序列图像中将变化区域提取出来。运动区域的有效分割对于目标分 类、跟踪和行为理解等后期处理非常重要,因为后期处理过程仅仅考虑图像中对应于运动区 域的像素。然而,由于背景图像的动态变化,如天气、光照、影子及混乱干扰等的影响,使 得运动检测成为一项相当困难的工作。-The purpose of motion detection from image sequence changes in the region will be extracted. Sports region segm

Image Segmentation.
A central problem, called segmentation, is to distinguish objects from background [10]. For intensity images (ie, those represented by point-wise intensity levels) four popular approaches are: threshold techniques, edge-based

提出了一种复杂背景下的多车牌图像分割和识别方法,首先采用统计和特征匹配相结合的方法进行背景提取,将可能存在车辆的区域提取出来;然后分别对可能的车辆区域进行局部边缘检测,并使用车牌的先验知识确定车牌的位置和单个字符分割,包括车牌倾斜时的字符分割;最后使用PCA和神经网络相结合的方法精确识别车牌。-Proposed a multi-plate image segmentation and recognition method under a complex background, the first

类间方差法对噪音和目标大小十分敏感,它仅对类间方差为单峰的图像产生较好的分割效果。
当目标与背景的大小比例悬殊时,类间方差准则函数可能呈现双峰或多峰,此时效果不好,但是类间方差法是用时最少的。-Variance between class size of the noise and the target is very sensitive, it only to the between class variance to unimodal images produce better se
