Embodiment Construction

[0043] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] An embodiment of the present invention provides a method for recognizing a handwritten form. The purpose of form recognition is to convert the form contained in the original input that cannot be understood by the computer into a structured form that the computer can understand, and determine the required value for each cell of the form. Included content. Table recognition goes through five steps in sequence: stroke sampling, graphic segmentation, stroke grouping, stroke segmentation into line segments, and table analysis, which will be described in detail below.

[0045] refer to figure 1 , is a flowchart of a method for recognizing a handwritten form according to an embodiment of the present invention. Among them, the ou...

Abstract

The invention discloses a method and a device for identifying a hand-written table, which solve the problem that the prior handwriting identification technology is imperfect in identifying the hand-written table. The method comprises: acquiring initial input as strokes to be analyzed; identifying nonverbal strokes from the strokes to be analyzed; splitting the nonverbal strokes into line segments; judging horizontal line segments and vertical line segments, and judging whether the horizontal line segments and the vertical line segments form a closed rectangle and whether the inside of the rectangle at least comprises a horizontal line segment or a vertical line segment, wherein line segments forming the closed rectangle are table boundary lines and the horizontal line segments or the vertical line segments in the closed rectangle are inner table lines if the inside of the rectangle at least comprises the horizontal line segment or the vertical line segment; and utilizing the table boundary lines and the inner table lines to construct a table structure, and filling the table content. The method and the device realize identification of the hand-written input table through the steps of stroke sampling, splitting of pictures and text, grouping of the strokes, splitting of the strokes into line segments, and table analysis.

Description

technical field [0001] The invention relates to pattern recognition technology, in particular to a method and device for recognizing handwritten forms. Background technique [0002] In the field of pattern recognition, identifiable information includes graphics, images, characters in various languages, tables and other forms, among which the technology of recognizing handwritten input, as an aspect of pattern recognition, has been widely used. Handwriting recognition technology is based on the recognition of handwriting input strokes, and converts the information input by people with the help of some equipment into a form that can be read and directly processed by computers. [0003] At present, the most widely used handwriting recognition technology is the recognition of words and other characters. Character recognition and processing technology developed earlier, and now it has developed to the application stage, such as the application of handwriting input methods in mobi...
