Problems solved by technology

[0005] However, in the above-mentioned process of character recognition, each character in the file must be compared with all the characters in the character database one by one, which will consume a lot of computing resources and increase the processing time of character recognition
In addition, the above-mentioned non-differential comparison method is very likely to cause misjudgment of characters due to noise interference, and cannot effectively improve the relative position of characters between characters or between characters and printing lines. Recognition rate and recognition speed

Embodiment Construction

[0029] Usually, when writing English-language characters, according to the characteristics of the font, the size and position of the written characters will be adjusted or arranged according to a certain trajectory. These hidden "reference lines" are similar to those when learning to write these characters. The four straight lines printed on the notebook, as long as users write characters according to these straight lines, they can write neat and clear articles. Similarly, these English-language characters will also follow these reference lines when they are printed, and these reference lines are also called printing lines in this article.

[0030] figure 1 is a schematic diagram of a printing line drawn according to a preferred embodiment of the present invention. Please refer to figure 1 , this embodiment is to define four printing lines according to the font of each printing character in the printed text "typeface analysis". These printing lines can be divided into top li...

Abstract

The invention provides a method for identifying characters. In the method, prior to identifying the characters, the characters to be identified are classified according to the relative position between the characters and the track. However, when the characters are identified actually, the characters corresponding to the classification of the characters in the character database are used for comparison. Therefore, the scope and number of the compared characters are reduced, and the accuracy rate and the speed of character identification can be improved.

Description

technical field [0001] The present invention relates to a character recognition method, and in particular to a method for group recognition of characters by printing lines. Background technique [0002] In the era of information explosion, ordinary people often need to read a large number of books or newspapers and magazines. When they see passages or key points worth saving, they usually archive them by photocopying or editing or directly mark them with a pen. For text workers, after reading an article, if they need to use the information in it, they must enter it into the computer by re-keying (Key-in) before they can edit or archive the information. The action is not only laborious and time-consuming. [0003] In order to solve this problem, some operators have developed optical recognition technology. Users only need to scan the document they want to save into a picture file with a general scanner device, and then use text recognition software to convert the text in the...
