Facial Feature Extraction for Accurate Cast Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing cast information in VOD are time-consuming and prone to errors, especially when human management is involved, leading to potential waste and inaccuracies in disclosing information before moving images are released.
Innovation Solution
A person information display apparatus that includes a characteristic extraction unit for facial features, a correspondence information extraction unit for matching extracted features with pre-stored data, an exclusion candidate setting unit for filtering analogous information, and a display unit for accurate and rapid presentation of cast information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If human management is used to specify and register cast information, then accurate information can be provided, but the operation takes a very long time
Solution Approach 1:
The patent replaces the mechanical human management system with an automated computer-based system that uses facial characteristic extraction and pattern matching algorithms to identify cast members, eliminating manual review while maintaining accuracy through automated comparison of facial features against a database
Solution Approach 2:
The system performs self-service by automatically extracting facial characteristics from moving images, comparing them with pre-stored characteristic information, and registering cast information without requiring human intervention at each step, thus significantly reducing operation time while maintaining accuracy
2Productivity
If cast information is registered in advance before determining disclosure, then information can be provided quickly, but the operation becomes wasteful if moving images are not disclosed
Solution Approach 1:
The system performs preliminary extraction of facial characteristics and preparation of characteristic information from moving images before the disclosure decision is made, so that when disclosure is confirmed, the cast information can be immediately provided without delay, while avoiding complete processing if disclosure is not planned
3Loss of time
If automated extraction is used to reduce operation time, then speed is improved, but errors may occur in extracted information
Solution Approach 1:
The system incorporates feedback mechanisms where extracted facial characteristics are compared against pre-stored characteristic information in a database, and the matching results are verified through multiple comparison iterations to ensure accuracy, allowing automated processing while maintaining high reliability
Solution Approach 2:
The system performs preliminary extraction and storage of accurate facial characteristic information during the production phase, creating a reference database that can be reliably used for automated matching later, thus ensuring accuracy is established before the speed-critical matching phase
