Embodiment Construction

[0080] Below in conjunction with accompanying drawing and take dynamic (pedestrian) face image recognition as example the present invention is described in further detail:

[0081] The hardware of the digital video dynamic automatic face recognition system consists of a video input device (1), an image acquisition card (2), a parallel processor (3) and a display screen (4). The video input device (1) can be a scanner, a digital camera, or a standard rate, non-standard rate, line array, area array video analog or digital camera, laser, X-ray machine, sonar, or a standard device that can acquire images . The image acquisition card (2) is a standard analog or digital image acquisition card, and can also be a digital video camera with a USB interface or a video editing card that can perform data exchange with the parallel processor (3) memory. On the PCI, ISA or corresponding standard structure bus of the parallel processor (3). The parallel processor (3) is a main control devic...

Abstract

The present invention relates to automatic human face-recognizing digital video system and belongs to the machine vision technology product. The system hardware consists of video input device, image acquiring card, parallel processor and display screen. The software consists of image acquiring module, cutting module, pre-treatment module, recognition module, parallel processing module, data storing and polling module, display module, alarm module and remote trnamission module. The system adopts the recognition method with implicit Markovian model to recognize static and dynamic face. The present invention can display face image intuitively while automatic recognition. It can be used in the plases which need to recognize human faces automatically.

Description

Technical field: [0001] The invention relates to a digital video face automatic recognition system, which belongs to a technical product in the field of machine vision. Background technique: [0002] Machine vision face recognition technology is a very challenging technology that uses machine vision to analyze face images and extract effective identification information to identify identities. Face recognition research involves machine vision, pattern recognition, neural network, physiology, anatomy, cognitive science and other disciplines. The research on face recognition began in the late 1960s [1], and became a scientific research hotspot in the 1990s. At present, face recognition is mostly a research topic, and it is not an active topic in the field of practical application. Face recognition is very difficult, mainly due to the rich facial expressions that change with age, the face image is affected by light, imaging angle and imaging distance, and the smooth transition...
