| 摘 要： | 图像投影是计算机视觉和图像处理领域中一项非常重要的工作。针对图像直方图投影分组算法在网上阅卷系统中的作用进行了分析。在图像信息识别过程中通过直方图投影分组的方法得到客观题答题区域,然后通过阈值分析即可得出所选答案,从而实现了客观题答案的自动识别,并通过delphi编程验证了实验结果。

| Abstract: | Mage projection in the computer vision and image processing field is a very important job.In this paper,the role of the image histogram projection grouping algorithm for online marking system were analyzed.In the identification process the image information through grouping histogram projection method obtain the regional of objective questions＇ answer,then the answer can be derived by the selected threshold analysis,in order to achieve the automatic identification of objective questions answers,and experimental results verified by delphi programming. |
