一种改进的背景提取与更新方法
An Improved Method on Background Extraction and Update
摘要
Abstract
The paper introduces an improved method on background extraction and update based on the features of background extraction and the disadvantages of the low aecurancy of mean algorithm and the bad real-time of mixture Gaussian model. The method obtains the initial background with probability distribution and statistics of histogram to reduce the impact of environmental changes. Then to increase the real-time and accurancy,it combines the Gaussian distribution with recursive algorithm to update the background. Compared with means algorithm and mixture Gaussian model,it is easier to be operated, has better real-time and aecurancy, and can effectively inhibit the noise caused by the slow targets.关键词
