Embodiment

[0061] The whole scheme mainly includes two processes of training and recognition. In order to describe the specific implementation of the invention in detail, we take the entry control of the smart room as an example to illustrate. Assume that the smart room is a confidential place that requires permission to enter, and it only allows some specific people to enter. Therefore, we can install a fixed camera in the corridor at the entrance of the room to capture the gait sequence of the incoming person, and use the present invention to realize the authentication work based on the gait. If the visitor can be effectively identified, the door will be automatically opened to allow entry; otherwise, entry will be refused, or alarm measures will be added.

[0062] As far as the training process is concerned, our aim is to first create a database of gait characteristics corresponding to these privileged individuals. Firstly, the surveillance camera is used to capture a series of gait ...

Abstract

The far distance identity identifying method based on walk includes two processes of training and identifying. The training process includes the steps of obtaining training walk sequence, spatial contour cutting, shape and distance signal extraction, main component analysis, personalized physique characteristic extraction to extract visible personalized characteristic as additional characteristic for final vertification of walk classification, and obtaining trained walk data base. By means of statistic pivot element analysis method, far distance identify identifying system based on walk behavoir is realized. The present invention utilizes also improved background reduction method, characteristic space transformation of motion contour, and correlation identification or nearest neighbour rule in the characteristic extraction.

Description

technical field [0001] The invention belongs to the field of pattern recognition, in particular to a long-distance identity recognition method based on gait. Background technique [0002] With the rapid development of modern technology, the use of cameras to monitor dynamic scenes has long been widely used in all aspects of society, especially those sensitive to security requirements, such as national defense, communities, banks, military bases, etc. Visual monitoring of dynamic scenes is a frontier research direction that has attracted much attention in recent years. It detects, recognizes, tracks targets and understands their behavior from image sequences captured by cameras. Although the surveillance camera, which is an extension of human vision, has been widely used in commercial applications, it has not fully utilized its role as a real-time and active surveillance medium. Therefore, it is increasingly urgent and necessary to develop an automatic and intelligent visual...
