一种改进的运动目标检测方法研究

Research on the Detection Method of Improved Moving Target

简要介绍运动目标检测技术的常用方法,采用自适应阈值和有限帧均值方法对基于背景差分和帧间差分相结合的检测方法进行了改进,有效避免了采用经验阈值的非自适应性,同时对于视频序列的初始帧中含有运动目标时初始背景建立不准确的缺陷进行了有效弥补。

Firstly, the ordinary techniques of moving target detection are briefly introduced in this paper. Then an improved method of moving objects detection based on background subtraction and frame difference is achieved by using a sell-adapt threshold and the means of limited frames method. It can avoid effectively the inadaptability when use an experiential threshold, and make up the limitation when the video sequence contains a moving target at the first frame.
