Online Marking-based Image Processing And Recognition Applications

With wide application of computer, national department and institution of education and examination applies computer information technology gradually. There are subjection topics and objective topics in all kinds of examinations. The part of objective topics adopt selective topics generally. We always grade the parts of objective topics with OMR, the method is accurate, high efficiency and the result almost is no error, but the parts of subjective topics check the students comprehension and expression capacity ,so the standard is flexible and the different teachers have different thoughts. All the factors increase the difficulties that control the error to grade the subjective topics. Aiming at soling the problem, since 2001, with more years examination arrangement and image process technology. We research and develop the technology of network grade without paper.Computer grade management system administer the each result, so it can control the grade error effectively, and make the grade work more open, fair and just.Network grade use the last scientific research achievement in computer fields. Based on high speed scanning and OCR, OMR, BAR recognition technology. Computer image high speed storage and process technology and network communication technology can realize the recognition of objective topics and the automatic distribution of subjective topics, so it also can realize to grade subjective topics, control the error and arrange the quality. The teachers grade the result on the computer screen.Network grade request OMR technology, OCR technology, Image process, BAR recognition and great capacity storage .At last, it will apply distinct 256 gray image and the objective topics for grade system.The research of digital image process technology is very popular in international recently. It has great theoretical profundity and applied value. But how to apply the technology process of examine files. It has a little research , although the technology has practicality, but the effect is limited.This paper research image process and recognition technology. And it use theimage process and recognition technology in the Network grade successMly. This paper aim at the research and use about file image process subsystem of network system.
