Cross-checkpost pedestrian identification system and method based on dynamic obvious feature selection

Abstract

The invention relates to a cross-checkpost pedestrian identification system and method based on dynamic obvious feature selection. The system comprises a city checkpost video acquisition module, a pedestrian detection and tracking module, a multi-feature extraction module, a feature excavation module, an obvious feature selection module and a pedestrian identification module. The invention also relates to a cross-checkpost pedestrian identification method based on dynamic obvious feature selection. The beneficial effects of the system and method are that feature information can be selected dynamically; the system does not use the mode of directly fusing multiple features, but uses the mode of fusing the multiple features, which have the highest pedestrian identification discrimination, found by carrying out feature uniqueness degree analysis and processing on various feature information, and thus the problem of unreliable identification of pedestrians by utilizing a single feature is solved; and through the system, redundancy feature information of pedestrian identification is removed, and the features having the highest pedestrian identification discrimination are found, and thus robustness of pedestrian identification is improved.

Description

technical field [0001] The invention relates to the technical field of pedestrian recognition in intelligent traffic monitoring, in particular to a cross-checkpoint pedestrian recognition system and method based on dynamic selection of salient features. Background technique [0002] With the launch of the safe city strategy, a large number of network surveillance cameras have been installed on various traffic arteries. When an incident occurs, staff are required to search for suspicious target pedestrians from a large number of surveillance video images. Faced with massive surveillance videos, the staff will inevitably feel boring. If the staff stares at the monitoring screen of the screen for too long, it will inevitably cause eye fatigue, and the experience or interest of each staff member will lead to inconsistency in results, which will eventually make it difficult to track suspicious pedestrian targets. [0003] Cross-checkpoint pedestrian recognition refers to pedest...
