Abstract

The invention relates to a digital signal processor (DSP)-based face detection method. The method comprises the following steps of: intercepting images from a dynamic video; extracting key information; and finding characteristic points by using the key information according to a topological relation between an entire face and each part based on the integrity attribute of a model by an image processing measure so as to finish overall face detection. A system hardware part consists of a front end image acquisition part, an information processing part and a back end, wherein a charge coupled device (CCD) camera with infrared image pick-up function is adopted by the front end image acquisition part; a BF533 processor is adopted by the information processing part; and the back end connects a television with a DSP platform and directly displays a face detection result. A software part programs by using a Visual DSP++ developing environment so as to realize data collection, processing and output control.

Description

[0001] The technical field [0002] The invention relates to a face detection method based on a DSP platform, which can be applied to fields such as face recognition, security access, and video surveillance. The present invention captures images from dynamic videos and uses image processing methods to focus on the overall attributes of the model. The topological relationship between the whole face and each part, extract and use key information to find feature points to complete face detection. Background technique [0003] The problem of face detection originally originated from face recognition, and the research on automatic face recognition can be traced back to the 1960s and 1970s. After decades of tortuous development, there have been relatively successful methods for automatic face recognition, which are becoming more and more mature. A complete automatic face recognition system should include three basic processes: face detection, feature extraction, and matching recogn...
