The Research Of A System Based On Electronic Examination Inspection Absent, Generation Of Test

Human detection and face recognition technology is based on the visual analysis and vital component of its intelligent video surveillance, human-computer interaction, video conferencing and many other areas has a very broad application prospects and great commercial value. Intended to be put into this project to build an electronic examination inspection system, based on the introduction of the human body detection and face recognition technology. Try statistics on the number of examination to determine the number of absent, and for the use of human face recognition, recording, comparison and to determine whether there is the phenomenon of generation of test, the electronic examination inspection system to more effectively support the examination management, improve the utilization rate, but also reduces the requirement for invigilators.In this paper, the human head detection and face recognition technology to do a thorough related research, providing a complete system based on electronic examination inspection absent, generation of test warning video analysis system solutions. Specifically, the main work and results are as follows:1. For the detection of the human head, in-depth study of the various shape-based detection Hough transform. Through analysis of assay results after the final selection of the GHT (Gradient Hough Transform) method as a nearly circular outline head detection method. While for the corresponding improvement GHT. Experiments show that:the improved GHT contour feature extraction method satisfies the system absent detection rate and real-time requirements.2. For face recognition, using a variety of image processing algorithms for image feature extraction do preprocessing. In edge detection, the rational use of the geometric position distribution of face, the eyes, mouth and other features to partition bits feature extraction efforts and increase the accuracy of feature extraction3. In the above head detection and face recognition on the basis of relevant technical studies, design a system based on electronic examination inspection absent, generation of test warning video analysis system.
