A human body retrieval method and system

Abstract

The invention discloses a search method and system for a human body. The method comprises the following steps: a picture existence judging step, a first search step and a second search step; during the picture existence judging step, judging the fact whether a picture of a human body to be inquired exists or not, if yes, entering the first search step, otherwise, entering the second search step; during the first search step, using the apparent characteristics of the human body underlayer of the human body to be inquired for screening the human body in a human body database, and generating a first search result; according to the first search result, using the set of top attribute characteristics of the human body to be inquired for screening the human body in the first search result, generating the final search result, and completing the search; during the second search step, confirming a search mode, using the top attribute characteristics of the human body to be inquired for screening the human body in the human body database according to the search mode, generating the final search result of the human body database, and completing the search. Through the adoption of the search method, the human body is searched more accurately and more quickly.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a human body retrieval technology based on the underlying appearance characteristics of the human body and the high-level attribute characteristics of the human body. Background technique [0002] In recent years, with the emergence of social terrorist incidents such as the "7 / 7 London Bombing" and "Moscow Airport Bombing", the issue of security in public places has been raised to a new level. The popularity of monitoring camera equipment provides a new way to prevent and deal with security problems, that is, by detecting the frequency and status of the same person in different areas. On the one hand, in the prevention of security issues, by analyzing the frequency of pedestrians in different positions and the change of appearance (for example: from backpack to bag loss), suspicious and criminal objects can be found; on the other hand, by Check the surveillance cameras around the ...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to solve the problems of inaccurate matching and poor real-time performance of the underlying human body appearance feature matching in the existing human body retrieval technology based on examples (human bodies to be queried), and propose a method based on human body underlying appearance features and A human body retrieval method and system based on high-level human body attribute features, in which retrieval results are retrieved through traditional low-level human body apparent features, using the robust high-level human body attribute features to filter out some retrievals that are different from the high-level human body attribute features of the human body to be queried results, and / or reorder the search results according to the matching degree of the high-level attribute features of the human body to obtain more accurate search results
