Analysis Of Video Monitoring Suspected Cheating On Exam

Video processing and analysis as an important field of computer vision research, has attracted more and more researchers’attention. Video processing system based on electronic examination inspection analysis is the use of computer vision, image processing, pattern recognition and machine learning techniques for video image analysis and understanding. In this paper, the video processing system based on electronic examination inspection analysis examination of suspected cheating, such as peek, passing notes, etc., and establish better supervision examination rules, the anti-air defense and technology combine to prevent and combat fraud and discipline, reducing the test chamber invigilator in the number of visits back and forth, for the candidates to create a good environment for the candidates.In this paper, the use of edge lines primitives identified goals for synchronized split. When the active base model or mixed initiative based model to detect the target after the first use of the segmentation algorithm primitive edge lines constitute the initial outline goals, and then continued refinement of the initial contour and, ultimately, more precise target outer contour. This paper presents an enhanced initiative for target tracking base model. The model includes the target color block edge features and characteristics, which uses an active base edge features to describe the characteristics of the color block color histogram used to describe and measure by defining a unified way out of these two types of feature extraction. In order to meet the needs of tracing paper constitutes not only in models made improvements, but also the base model of active deformation capacity of each element, or the ability to expand the initiative known as the reinforcing active base model during tracking each primitive direction of movement of the object can be in a larger space, searches for the best matching position. At the same time, the relative position between the base element constrained by the model. Taking into account the target appearance may change due to their own motion or environmental changes and other reasons, this paper also designed the update algorithm for the model so that it can adapt to changes in target motion generated.Finally, this paper presents a prototype electronic examination inspection video processing framework and the overall integrity of the system design, and the main function modules of the system to perform detailed analysis and explanation.
