This text mainly is to panorama video frequency picture, the usage partitions new calculate way automatically according to the video frequency object of timespace consociation at preparing processing stage's ash to video frequency sequence degree diagram to carry on a partial contrast degree to strengthen a processing, increasing foreground object and the contrast degree of background, the filter which passes 3 ×s 3 templates filters in addition to contrast degree strengthen after of lead go into of a little amount 噪 voice;Then aim at the circumstance of complicated background, the calculate way in the text puts forward the covariance characteristic backlog which makes use of immediately signal to get the background that the calculate way needs, overcoming the irregularity that the handicraft obtains background, carrying out a background information to obtain automatically;The standpoint put forward a background backlog finally to categorize a discussion in the process, solved object stop sport time is longer result in the partition throw the problem for losing.

本文主要是对全景视频图像，运用基于时空联合的视频对象自动分割新算法，在预处理阶段对视频序列的灰度图进行局部对比度增强处理，增加前景物体与背景的对比度，通过3×3模板的滤波器滤除对比度增强后的引入的少量噪声；然后针对复杂背景的情况，文中的算法提出利用随即信号的统计特性积累得到算法所需的背景，克服手工获取背景的弊端，实现背景信息的自动获取；最后提出背景积累过程中分类讨论的观点，解决了物体停止运动时间较长时造成分割丢失的问题。
