Problems solved by technology

[0003] However, because the texts in various picture forms usually use different fonts, and currently only one set of font libraries is used when comparing the graphic metatext with the font text, if the font of the graphic metatext and the font in the font library When the fonts are different, the accuracy of character recognition is not high; if multiple sets of font libraries are used, each graphic element text will need to be compared with each font in multiple sets of font libraries. Compared with the text, the workload is very huge

Embodiment Construction

[0010] Below the present invention is further described:

[0011] The picture text recognition method provided by the present invention is as follows: the text area on the picture selected by the user is read in the form of the current picture. The text area selected by the user is regarded as a picture to be processed; then, each graphic element text in the picture to be processed is selected separately, and the selection is in the form of a rectangular frame, from top to bottom, Select the primitive text one by one in order from left to right, and the frame line of the rectangular frame is tangent to the top, leftmost, bottom, and rightmost ends of each primitive text; After a primitive text, compare it with each font text in the font library corresponding to various conventional fonts, find the font text with the closest similarity, output the font text in the form of editable text, and record the similarity The font library where the font text with the highest accuracy is...

Abstract

The invention provides a picture character recognition method. The picture character recognition method comprises the following steps of: reading a text area, on a picture, frame-selected by a user in a current picture form; respectively selecting each pixel character in the frame-selected text area; comparing the first pixel character in the frame-selected text area with each matrix character in matrix libraries corresponding to various conventional fonts so as to find matrix characters with the highest similarity; and recording the matrix libraries of the matrix characters with the highest similarity, defining the matrix libraries as standard matrix libraries, respectively finding the matrix characters with the highest similarity in the standard matrix libraries, and outputting the matrix characters with the highest similarity in an editable character form. According to the method, the character information in pictures can be correctly and efficiently recognized.

Description

technical field [0001] The invention relates to the field of graphic and text software, in particular to a method for identifying text in pictures. Background technique [0002] For the text on the picture, in many cases, it needs to be copied and used in large sections. Therefore, it is necessary to first convert the text in the form of the picture into editable text through software methods; in this process, the current method used is, Using a set of font library, compare each graphic element text intercepted in the picture with each font text in the font library, and output the most similar font text in the form of editable text, so that users can get what they need Editable text. [0003] However, because the texts in various picture forms usually use different fonts, and currently only one set of font libraries is used when comparing the graphic metatext with the font text, if the font of the graphic metatext and the font in the font library When the fonts are differe...
