Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing methods for text replacement on electronic devices require manual smearing of original text and limited font and color selection, leading to inaccurate smearing and inconsistent display effects, making the editing process complex and rigid.
Innovation Solution
An image processing method that identifies a text region on a target image, trains a font style model, and replaces the original text with user-input text matching the original font style, ensuring seamless integration and consistent display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual smearing operation is performed to remove original text, then text replacement can be realized, but the operation complexity increases and smearing accuracy deteriorates
Solution Approach 1:
The system performs automatic text region identification and smearing operations without requiring manual user intervention. The electronic device automatically detects text regions, determines smearing parameters, and executes the smearing process, eliminating the need for users to manually smear text while maintaining accurate text removal.
Solution Approach 2:
The manual mechanical smearing operation is replaced by an automated image processing system that uses algorithmic text region detection and automatic smearing execution. This substitution transforms the manual mechanical process into an automated computational process, improving both ease of operation and smearing accuracy.
2Ease of manufacture
If manual smearing operation is performed to remove original text, then text replacement can be realized, but smearing precision deteriorates due to difficulty in controlling smearing range
Solution Approach 1:
The system uses feedback mechanisms where the text region identification results are used to automatically determine and adjust smearing parameters. The identified text region boundaries provide feedback that guides the smearing operation to precisely cover only the text areas, ensuring accurate text removal without affecting surrounding image content.
Solution Approach 2:
The imprecise manual smearing process is replaced by an automated system that uses image processing algorithms to precisely identify text regions and calculate optimal smearing parameters. This substitution enables precise control over the smearing range, ensuring that only the text regions are affected while maintaining high smearing precision.
3Productivity
If only default set font and color are selected for replacement text, then text replacement can be completed, but display effect consistency deteriorates
Solution Approach 1:
The system applies local quality by analyzing the specific font and color characteristics of the original text in the identified text region and applying these same characteristics to the replacement text. This ensures that the replacement text matches the local visual properties of the original text, achieving display effect consistency while maintaining efficient automated text replacement.
Solution Approach 2:
The system dynamically changes the font and color parameters of the replacement text to match the original text characteristics. By automatically extracting and applying the original text's font type, size, and color parameters, the system ensures display effect consistency while maintaining high text replacement efficiency through automated parameter adjustment.
4Ease of operation
If automated text region identification is implemented, then operation convenience improves, but device complexity increases
Solution Approach 1:
The electronic device integrates multiple functions including text region identification, smearing parameter determination, and smearing execution within a single unified system. This multi-functionality allows the device to perform automated text replacement operations without requiring separate specialized components, improving operation convenience while managing device complexity through functional integration.
