Research On The Tracking And Guidance Of Chinese Character Writing Based On Template Stacking

The tracking guidance of Chinese character writing is of great significance to assist in the automatic teaching of Chinese character writing.In the automatic teaching of Chinese characters,tracking and guidance of writers,timely detection of problems in the writing process and suggestions for improvement can provide students with real-time writing feedback,and also help teachers further understand the state of students'writing knowledge.Provide guidance.Existing methods of Chinese character writing instruction have not grasped the characteristics of Chinese characters properly,or they cannot track and guide the errors in the process of Chinese character writing,which is far from meeting the needs of Chinese character automated teaching for writing instruction.Inspired by this,this paper studies the method of Chinese character writing tracking guidance based on template overlay,extracts feature from template overlay based on track point set and feature markers,and sets the threshold of Chinese character tracking guidance based on feature similarity to establish Chinese characters.The research of writing tracking guidance system and experimental verification is carried out.From the perspective of the three strokes,parts and the whole of the Chinese character,the stroke of the writing process,multiple strokes,one part,and multiple parts are superimposed to the final whole character,and the characteristics of the Chinese characters are extracted based on the template superimposition.Taking into account the requirements of correctness and integrity judgment,the corresponding feature extraction is combined with the track point set and mark in XML.Then,the Chinese characters are pre-processed from the point of eliminating redundant point sets and noise reduction of point sets.For the pre-processed point set,the template features are extracted from five levels of one stroke,multiple strokes,one part,multiple parts,and whole characters.The characteristics of a stroke include stroke length,direction,radian,absolute position,and stroke rhythm.Multi-stroke features include intersections,connections,adjacent relationships,relative positional relationships,and special stroke length relationships between strokes.A part includes part size,aspect ratio,and absolute position.Multiple parts include relative positions and size ratios between parts.The whole word aspect includes the absolute position,size,aspect ratio,and smoothness of Chinese characters.After extracting features by superimposing templates,a Chinese character tracking guidance system was established.Methods for comparing the characteristics of user Chinese characters with standard template Chinese characters,including ratio method and difference method.Iterate through all the features to get the feature similarity set,and display the final tracking instruction sentence according to the weight.The experiments show that the Chinese character writing tracking guidance method based on the superimposed template has certain feasibility and robustness,which shows that the algorithm is effective,but it needs to be improved.
