The Research of Pose Varied Pedestrian Detection and Recognition plex Scenes Abstract
The Research of Activity Analysis Based on VStop Visual Words plex Dynamic Scenes
Abstract
plex scenes, activity analysis, especially rare activity analysis is the basic topics puter vision. In the research, pattern recognition, artificial intelligence, image processing and other areas of knowledge is necessary. The knowledge of how to effectively integrate those method is worth to study for the activity analysis knowledge. The subject of strong applications (Intelligent Caring, Intelligent Security, Intelligent Transportation, Intelligent City, etc.) adds to its theoretical significance and application value. Paper focuses on the fixed camera in plex scenes, the scene changes, the target variety of different forms of exercise lead to a difficult target tracking, behavioral modeling difficulties, rare behavior is difficult to model, pause, velocity anomalies, abnormal direction. Its contents are as follows: visual word generation algorithm, rare behavior analysis and online rare activity detection, the main work of this paper is summarized as follows:
Traditional visual word usually using only the direction information and location information, lacking of velocity information and context information. The lack of target's speed information, some behaviors can not be effectively modeled. For
