[0004] Although this method uses foreground detection, it does not make full use of the position feedback of the actual target in the video stream and the prediction of the number of targets in the area, and the real-time detection is poor; at the same time, this method only uses a feature extraction method to improve detection. Rate intelligence is realized through the selection of samples and the number of features, and the effect is not obvious; this method has no face recognition evaluation and filtering mechanism, and the false detection rate is high

Description
technical field [0001] The invention belongs to the technical field of face detection, and in particular relates to a real-time face detection method based on an embedded system. Background technique [0002] With the rapid development of semiconductor technology and the continuous emergence of new calculation methods, the current intelligent analysis algorithms have gradually moved from the back-end PC equipment to the front-end, and various intelligent terminal products have emerged. Face detection is a smart device. The main function is to detect and capture faces in real time, which not only greatly improves the user experience, but also reduces the pressure on post-storage, speeds up retrieval, reduces usage costs for customers, and improves work efficiency. In the current highly competitive monitoring field , is undoubtedly the best choice. [0003] The face detection methods in the prior art are all based on foreground detection, feature extraction and classification...
