Handwriting Manuscript Line Division With Abnormal Stroke Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for line separation of handwriting texts from electronic writing panels face challenges due to variations in writing habits and environmental effects, leading to issues such as unequal stroke orders, abnormal strokes, and difficulties in accurately dividing lines.
Innovation Solution
An auto-line-division system that records stroke coordinates and times, uses a mainframe with processors and memory to process manuscripts, includes units for calculating standard heights and widths, deleting abnormal strokes, and employs pre-division, special line handling, overlarge line re-division, and space incorporation to improve line division accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional line separation methods are used, then the basic line division function is achieved, but accuracy deteriorates due to abnormal strokes and writing variations
Solution Approach 1:
The system performs preliminary processing to identify and delete abnormal strokes before conducting line division. This preliminary action removes problematic elements (abnormal strokes caused by writing habits or environmental effects) that would otherwise interfere with accurate line separation, thereby improving both accuracy and reliability of the line division process
Solution Approach 2:
The system converts the harmful effect of abnormal strokes into a benefit by using them as identification targets for deletion. By detecting strokes that deviate from normal patterns (caused by writing variations or environmental factors) and removing them, the system transforms these previously harmful elements into an opportunity to improve line division accuracy
2Productivity
If simple line division is performed, then processing speed is maintained, but line division efficiency deteriorates due to multiple processing steps needed
Solution Approach 1:
The system segments the line division process into distinct functional units: abnormal stroke detection unit, line division unit, and correction unit. This segmentation allows each unit to specialize in a specific task, improving overall processing efficiency while maintaining manageable complexity through modular design
Solution Approach 2:
The abnormal stroke detection unit serves as an intermediary between the input handwriting data and the line division unit. It pre-processes the data by identifying and removing abnormal strokes, providing cleaner input to the line division unit and reducing the need for complex correction mechanisms later in the process
3Measurement precision
If multiple lines are divided into one single line, then line division simplicity is maintained, but measurement precision deteriorates
Solution Approach 1:
The correction unit implements a feedback mechanism that evaluates the results of line division and identifies cases where multiple lines were incorrectly merged. Based on this feedback, the system performs corrective actions to separate the lines properly, thereby improving measurement precision while maintaining operational simplicity through automated correction

AI summary
An auto-line-division system for handwriting manuscript for line-division of a handwriting manuscript from an electronic handwriting input panel is provided. Generally, in writing, various conditions will generate, such too large or too small words, isolation words, reversal strokes, etc. The system could process these problems in writing based on the setting of a standard line height and a standard line width. The edges and features in division of lines are detected and some values are calculated for correction of the line division so that efficiency of line division is promoted. Another, problems induced in the first line division is taken into consideration, and the problem of multiple lines due to mistake line division can be further correct to one single line. These problems could is corrected so as to promote the accuracy in line division.
