Handwriting track modification method

Abstract

The invention relates to a handwriting track modification method, which comprises the following steps of: (1) forming a two-dimensional coordinate dot matrix on a screen of electronic equipment by a track written on paper through a technical means, and recording and storing the two-dimensional coordinate dot matrix; (2) carrying out model definition on a specific intention track of handwriting deletion and modification, synchronizing the intention track to an identification program in a human body handwriting mode, and matching the program with a defined model; (3) performing intention judgment on the deleted and modified intention track coordinates and the coordinates written normally before, and judging a character track needing to be modified or deleted through the action intention mathematical model, that is, synchronizing the character track to two-dimensional coordinates in the system; and (4) matching the modified or deleted character tracks, screening out the character tracks needing to be deleted or modified according to a defined modification model in combination with the action intention mathematical model, judging that the translated standard characters are recognized,realizing track tracking, and performing the next action, deletion or modification by a program. The method has the advantages that the deviation can be reduced, and the accuracy is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for modifying handwriting traces. Background technique [0002] The handwriting trajectory modification algorithm realizes the text modification of the trajectory recognition by handwriting input, that is, through the program algorithm, the electronic re-editing of the written text is realized by handwriting, replacing the function of deleting or modifying the electronic text during the input process of the operating system (manual operation The system screen or keyboard can be used to edit the text twice), so as to simplify the realization of text recognition when writing on paper and conveniently modify the recognized text on the electronic screen. [0003] For example, when a user writes with a pen on paper, the writing track is synchronized to the electronic screen through technical means. During this process, the writing track is recognized and translated by ...

Problems solved by technology

However, if the previously handwritten text or symbols need to be modified or deleted during the writing process or after the writing is completed, the text recognized by the text recognition system needs to be modified or deleted at the same time. The existing trajectory tracking algorithm calculates the intention The coordinates in the trajectory, and then select the text closest to the coordinates to modify or delete, but the text that needs to be modified or deleted by this algorithm is not accurate, and there is a certain deviation
