基于Matlab的答题卡识别技术研究

浙江传媒学院本科毕业论文基于Matlab的答趣卡识别技术研究RESEARCH ON ANSWER CARD RECOGNITIONTECHNOLOGY BASED ON MATLABAbstract:In the high-speed development of the Internet era,people are receivinginformation all the time,so the ability to obtain and respond to information in theenvironment is very necessary.Among them,text informationtakes up the vast majority.If theinformation processing system can analyze the surrounding environment as much as possible,especially the text information in the environment,then the information acquisition processwill be more simple and fast.In this paper,the answer card recognition as an example,usingMATLAB software to realize the answer and personal information recognition,scorecalculation and output.Through MATLAB software,the digital image is acquired,preprocessed edge detection,Hough detection line,smooth filtering,morphological filtering,region segmentation and marking,and a series of operations.The corresponding algorithm isedited and a integrated GUI interface is excogitated.Using MATLAB software to simulateand test,the accuracy of the relative ratio between the output score and the real score is 100%,which also fully ensures the fairness and justice of marking,and reduces the burden of manualmarking.Keywords:Matlab;digital image processing;answer card;answer recognition
