Embodiment Construction

[0016] Such as figure 1 As shown, in one embodiment, the face recognition system of the present invention includes: a video input interface, which is used to enable the face recognition system to be connected to a face image data acquisition unit such as a camera to receive a face image data. The face recognition operation processor is used to process the received face image data and complete the recognition work; because the recognition operation process of face image data is relatively complicated, it generally includes: face data preprocessing (such as face image processing) Data format conversion, brightness adjustment, etc.), face detection (mainly used to determine the data representing the face in the face image data), face positioning (mainly used to locate the position of the organs in the face data) and face features Steps such as vector extraction, comparing with pre-saved features to judge whether the recognition is successful, etc., so in order to realize the who...

Abstract

The invention discloses a human face identification system which comprises a video input interface which is connected with a human face image data acquisition unit and used for receiving human face image data, a human face recognition arithmetic processor used for processing the received human face image data and finishing identification work, a microprocessor unit which is connected with the human face recognition arithmetic processor and used for being responsible for processing various external interfaces, and a communication interface used for being responsible for communication with various application equipment. The human face identification system lowers the complexity of the structure, reduces the size, enhances the stability and the reliability of the system simultaneously and further lowers the application threshold of human face identification, thus being easier to be popularized and applied.

Description

technical field [0001] The invention relates to a face recognition system, in particular to an embedded face recognition system. Background technique [0002] Compared with other human biometric identification technologies, face recognition technology has its unique advantages. It is fast, simple, non-invasive and does not require passive cooperation of people. Except for face recognition technology, other human body biometric recognition technologies are a kind of interference to people, and they all require passive cooperation of people. For example, fingerprint and palmprint recognition require people to put their hands on the glass surface, while iris recognition needs to irradiate people's eyes with laser light, voice recognition requires people to speak into a microphone, and handwriting recognition requires people to sign and so on. Face recognition does not need to interfere with people's behavior. It only needs a person to quickly walk in front of a camera, and his...
