利用huogh变换识别答题卡，算法运行成功。(Using huogh transform to identify answer sheets)

图像处理领域，基于Hough变化的答题卡识别(Recognition of answer card based on Hough changes in the field of image processing)

基于Hough变化的答题卡识别，已经调试成功，可直接使用(The identification of the answer card based on the change of hough has been successfully debugged and can be directly used)

本课题为基于MATLAB的不变矩答题卡识别。可识别学号，学科，答案，并进行分数统计，以及判断是否及格。后台可设置标准excel答案。经过灰度变换形成灰度图像、二值化处理、图像滤波、边缘检测、hough变换等预处理。带GUI交互式界面。(This topic is based on MATLAB moment invariant answer card recognition. Can identify student number, subject, answer, and carry out
