Connecting Paper to Digitization

How to monitor students' learning in daily learning behavior and guide teachers to teach more rationally are very important problems. While the digital teaching resources are popular, we can not ignore the information of traditional paper media. We design a homework processing system to solve the problems. First of all, we begin the operation from the acquisition side, by photo taking and image preprocessing, we make the homework picture with semantic meanings. Then we construct an answer reference system, which shows the answers of different kinds of incorrectbess as samples for teachers to refer to when correcting. Semantic pictures are dispatched to teachers handheld devices for intelligent and precise correct activities. We divide correct process into determining the degree of error and giving comments to evaluate and inspire students. Finally, we design a web page for homework data management and correction statistics to help teachers understand the homework completion status of students. The design of homework correction scheme is easy to deploy and can be used in most teaching environments.
