Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face swapping technologies require multiple videos of the same target object for training, making the process time-consuming and impractical, and often result in splicing defects such as mismatched interpupillary distance and inconsistent light and shadow, leading to distorted facial appearances.
Innovation Solution
An AI face replacement device that uses a processor, storage, and various modules such as a face swapping module with CNN and GAN, a light and shadow capture module, and an adjustment module to perform face replacement with a single clear face photo, optimizing light and shadow, and allowing for detailed parameter adjustments to correct facial features like eyes and teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional face swapping technology is used, then face replacement can be performed, but multiple videos of the same target object are required for training, making the process time-consuming and impractical
Solution Approach 1:
The patent uses a single clear face photo as a copy of the target object's facial features, replacing the need for multiple videos. The AI model extracts and learns facial characteristics from this single image copy, achieving face replacement without requiring extensive video training data.
Solution Approach 2:
The patent changes the training parameter from multiple videos to a single photo. By transforming the input data format and adjusting the training parameters accordingly, the system achieves efficient face replacement with significantly reduced training time and data requirements.
2Productivity
If traditional face swapping technology is used, then face replacement can be performed, but splicing defects occur such as mismatched interpupillary distance and inconsistent light and shadow, leading to distorted facial appearances
Solution Approach 1:
The patent implements feedback mechanisms where the AI model continuously adjusts and optimizes facial feature alignment during the replacement process. The system monitors parameters such as interpupillary distance and light-shadow consistency, making real-time corrections to eliminate splicing defects and achieve natural-looking results.
Solution Approach 2:
The patent dynamically adjusts multiple parameters including interpupillary distance, eye corner angles, and light-shadow distribution to ensure accurate facial feature alignment. By optimizing these parameters during processing, the system eliminates splicing defects and maintains high manufacturing precision in facial feature reconstruction.
3Manufacturing precision
If manual intervention and adjustments are made to optimize splicing defects, then facial appearance quality can be improved, but the workload for modification of the original picture becomes enormous, making modification less efficient
Solution Approach 1:
The patent enables the system to automatically correct splicing defects and optimize facial appearance without requiring manual intervention. The AI model performs self-adjustment of parameters such as light-shadow consistency and feature alignment, eliminating the need for labor-intensive manual picture modification while maintaining high facial appearance quality.
Solution Approach 2:
The patent replaces manual mechanical adjustment processes with automated AI-based processing. Instead of requiring operators to manually modify pictures to correct splicing defects, the system uses computational algorithms to automatically optimize facial appearance, significantly reducing workload and improving efficiency.
