Table Extraction from Touch Screen Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot edit contents drawn on touch control display screens after saving them as pictures, as the saved images do not retain editable format.
Innovation Solution
A method and device for table extraction that extracts screen pictures from touch control display devices, detects and processes table structures within these images, and establishes a matching relationship between the tables and text information, allowing the tables to be saved in a format that can be edited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen contents are saved as picture format, then the contents can be viewed after opening, but the contents cannot be edited again
Solution Approach 1:
The patent extracts table structures from screen pictures by detecting curve segments and identifying table boundaries, separating the table content from the image format to enable editable extraction of structured data
Solution Approach 2:
The patent changes the format parameter of saved contents from static picture format to editable table format with text information, allowing the same content to be both viewable and editable
2Ease of operation
If table extraction is performed on screen pictures, then editable table format can be obtained, but the processing complexity increases
Solution Approach 1:
The patent segments the table detection process into distinct steps: detecting curve segments, identifying table boundaries, extracting table content, and matching with text information, making the complex processing more manageable and systematic
Solution Approach 2:
The system automatically detects and extracts table structures from screen pictures without requiring manual intervention, making the complex processing transparent to the user while maintaining ease of operation

AI summary
The present disclosure provides a method for table extraction. The method includes: extracting a screen picture corresponding to a screen content of the touch control display device in response to an operation instruction; detecting the screen picture to obtain a second table corresponding to the first table contained in the screen picture; obtaining text information in the screen picture; and establishing a matching relationship between the second table and the text information to obtain the second table containing a text. When a user needs to save the screen content, the user may trigger extraction of the screen picture. Next, the second table corresponding to the first table in the screen picture and text information in the second table may be automatically extracted, and the second table and the text information are saved as a destination document.
