Abstract

The invention discloses a social intimacy determination method and system. The method comprises the steps of obtaining an image collected by a camera; Detecting face information in the image by adopting a cascade neural network; Determining sparse representation of the detected face information by adopting a convolutional neural network; adopting The sparse representation of the face information as input, and adopting a classifier to classify faces to obtain faces representing different persons; Taking faces of different persons as targets for tracking, and obtaining behavior information of each person, the behavior information comprising distance information between persons and conversation behaviors between persons; And determining the intimacy between the walking persons according to the behavior information of each walking person. According to the social intimacy determination method and system provided by the invention, the intimacy between the pedestrians can be automatically obtained based on camera monitoring.

Description

technical field [0001] The present invention relates to the fields of face recognition and behavior recognition, in particular to a method and system for determining social intimacy. Background technique [0002] Face recognition is one of the important applications of computer vision, specifically referring to the technology of automatic identity identification by computer by analyzing and comparing the visual feature information of faces. Compared with traditional biometric methods such as fingerprints and irises, face recognition has the advantages of non-contact, in line with human identification habits, strong interactivity, and not easy to steal. Therefore, in ensuring public safety, information security, financial security, companies and individuals There is a strong demand for property safety and superiority. [0003] At CVPR (the top conference in the field of computer vision and pattern recognition) in 2015, Google announced their face recognition algorithm. Taki...
