Solution Overview
Problem
Conventional methods for translating webtoon content into multiple languages face challenges in accurately recognizing speech bubbles due to their varied shapes and colors, leading to image damage and incorrect recognition of background elements as speech bubbles.
Innovation Solution
A method using artificial intelligence to train a speech bubble recognition algorithm, which learns to distinguish speech bubbles by processing webtoon images, normalizing styles, and assigning weights based on text presence and vector matching, allowing for accurate and quick recognition and translation of speech bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional text-based speech bubble recognition is used, then the recognition process is simple, but the recognition accuracy is low and background elements are mistakenly identified as speech bubbles
Solution Approach 1:
The patent transforms the speech bubble recognition problem from text-based detection to vector-based shape analysis. By converting closed curve shapes into vectors and comparing vector changes, the system achieves accurate recognition of speech bubbles regardless of text content, color, or background elements, resolving the contradiction between simple process and high accuracy
Solution Approach 2:
The patent replaces conventional text-based recognition mechanisms with an artificial intelligence-based vector analysis system. The AI learns to distinguish speech bubbles by analyzing the geometric properties and vector changes of closed curves, eliminating the need for text detection and avoiding misidentification of background elements
2Measurement precision
If manual translation with professional translators is used, then translation accuracy is high, but time consumption and cost are excessive
Solution Approach 1:
The patent implements preliminary action by pre-training the speech bubble recognition algorithm with extensive learning images before actual translation tasks. This preprocessing step enables the system to quickly and accurately identify speech bubbles in new images without manual intervention, achieving both high accuracy and efficiency in the translation workflow
Solution Approach 2:
The patent enables self-service automation where the AI system independently performs speech bubble recognition, text extraction, translation, and image reconstruction without human intervention. The system serves itself by automatically completing the entire translation workflow, eliminating the need for professional translators while maintaining efficiency
3Productivity
If automated speech bubble recognition is used, then processing speed is fast, but speech bubbles with various shapes and colors cannot be accurately distinguished
Solution Approach 1:
The patent changes the recognition parameters from text-based features to vector-based shape features. By representing closed curves as vectors and analyzing vector changes, the system can rapidly process images while accurately identifying speech bubbles of any shape, size, or color, resolving the contradiction between speed and accuracy
Solution Approach 2:
The patent implements feedback mechanisms where the AI system continuously learns from recognized speech bubbles and adjusts its recognition criteria. The system uses the vector change patterns of correctly identified speech bubbles to refine its algorithm, improving accuracy while maintaining fast processing speeds through iterative optimization
