公共场所暴力行为的光流场构建及分析方法
Optical Flow Establishment and Analysis of Violence in Public Places
摘要
Abstract
In view of the situation that in recognition of violence in public places, the previous method of detecting has the existence of miscarriage of justice to the static object or general physical contact.So in this paper, a public places violence detection method based on Lucas-Kanade optical flow method is proposed, and the effect of recognition in different parameters is analyzed.First, the feature points of two adjacent frames are detected and stored.Then, the optical flow field to reflect the motion state of objects will be constructed.Besides, in this paper, the effects of the three parameters on the optical flow are analyzed, which are the Pyramid decomposition layer, the optical flow computation window and the maximum optical flow direction of the Lucas-Kanade optical flow algorithm.The experimental results show that the analysis method for constructing optical flow field can effectively identify the occurrence of violence in public places.关键词
