Face recognition method based on video stream

Abstract

The invention discloses a face recognition method based on a video stream. The method comprises the steps that multi-frame continuous contrast recognition for high-definition videos is adopted to decode video data of monitoring devices, and data frames are separated to form image data of each frame video, so that the face recognition rate is substantially increased in an exponential order; face feature recognition processing is performed on each frame image to establish a probabilistic arrangement list of face recognition in each frame image; through calculation of fit-goodness list data of face recognition in continuously adjacent frame images, face information in the videos is locked, and then simultaneous recognition analysis is performed on faces of multiple targets to lower the omission rate of the face information; and according to the faces recognized in the video of each monitoring device, face recognition accuracy is calibrated again, so that a more accurate recognition effectis obtained. According to the method, through sufficient application of the monitoring devices, the big data control capability of a city administrative department based video monitoring is improved,and the automation degree is increased.

Description

technical field [0001] The invention belongs to the technical field of face monitoring and recognition, and in particular relates to a face recognition method based on video streams. Background technique [0002] China's security industry has experienced a development process of introduction, imitation, digestion and absorption, and innovation. After 30 years of development, China's security companies have experienced the era of analog monitoring, digital monitoring, and IP network monitoring, and are developing towards the era of high-definition intelligence. [0003] In the composition of China's security industry, video surveillance accounts for a large proportion, accounting for about 55%, access control accounts for 15%, anti-theft alarm accounts for 12%, and other categories account for 18%. Therefore, the intelligent application and technological improvement of video surveillance , will surely become the key factor and catalyst for China's security industry to move t...

Problems solved by technology

[0008] Therefore, with the increasing popularity of high-definition surveillance, clear surveillance video does bring greater convenience and performance to the public security department, but apart from the visual perception of the human eye and artificial image sorting, there is no effective face recognition method. method to facilitate big data personnel identification, tracking and management
