Abstract


Over the last decade , public places, the security situation is getting grim. As people gradually increase safety awareness , gait recognition by the extensive attention of researchers in the field of biometrics and important progress has important research significance and application value . Compared to other biometrics , gait without tie , remote access , difficult to hide other advantages , so that it can be effectively used in security-sensitive places , such as airports, banks , parking . Present , depending on the adopted gait characteristics , gait recognition is divided into two types: based gait recognition technology vision based gait tactile recognition technology . Based gait recognition technology vision earlier study , also presented many algorithms , but gait is a behavioral process Based the Visual Gait vulnerable itself and the outside world , the technology is difficult to achieve a good recognition performance and application in practical situations . Compared to the gait visual , the gait tactile feature has not susceptible to the influence of external factors , can be accurate, effective measurement of the Gait of structural parameters , etc. . Gait - based tactile recognition technology in its infancy stage , there is still much work to be in-depth and refinement . This work is mainly focused on the fusion algorithm based gait recognition algorithm for image sequence and gait visual information gait tactile information . We have established a multi- modal gait database . We developed a set of acquisition systems , synchronous gait pressure data were collected and gait image sequence , and collected data were preliminary processing , and laid the foundation for further work . The article proposes a gait recognition method based on the Hough transform . The method is the Hough parameter space to construct gait templates , making gait template reflects the limbs and other parts gait process unfolded segment information . In this paper, the multi- modal information fusion gait cascade method , fusion gait pressure information and gait image sequence information . Among them , the use of the Dynamic Time Warping to measure the degree of similarity between the gait pressure waveform .
