Makeup Simulation Using Facial Feature Point Coordinates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing makeup simulation technologies struggle to apply corrected makeup created by one user to another user due to differences in facial size, shape, and component arrangement, making it difficult to transfer the makeup image accurately.
Innovation Solution
A makeup supporting device that generates a simulation image by superimposing a makeup image on a facial image, includes a makeup correction unit for user input corrections, and a correction information recording unit that records these corrections using relative positions to facial feature points, allowing the corrected makeup to be applied to another user's face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional makeup simulation technology is used to apply makeup images to different users, then the makeup simulation can be performed on individual faces, but the corrected makeup created by one user cannot be applied to another user due to differences in facial size, shape, and component arrangement
Solution Approach 1:
The patent transforms the makeup image coordinates from absolute pixel values to relative coordinates based on facial feature points. By changing the coordinate system parameters from fixed image dimensions to dynamic facial landmark references, the makeup can be accurately applied to different users regardless of their facial size and shape variations.
Solution Approach 2:
The patent introduces facial feature points as intermediary reference elements between the makeup image and the user's face. These feature points serve as mediators that enable the transfer of corrected makeup by providing a common reference framework that adapts to different facial geometries while maintaining precise makeup placement.
2Productivity
If default makeup is used for simulation, then the makeup simulation can be easily performed, but the corrected makeup created by users cannot be transferred or shared between different users
Solution Approach 1:
The patent creates a universal coordinate system based on facial feature points that can accommodate both default makeup and user-created corrected makeup. This multi-functional approach allows the same system to handle different types of makeup (default and corrected) and enable their transfer across different users, eliminating the limitation of conventional systems that only work with default makeup.
Solution Approach 2:
The patent enables the copying of corrected makeup by recording the relative position information of makeup images with respect to facial feature points. This copied relative position data can be applied to different users' faces, allowing the corrected makeup created by one user to be accurately reproduced on another user's face while maintaining the same relative positioning.

AI summary
A makeup supporting device includes: a makeup presentation unit that generates a simulation image by superimposing a makeup image on an image obtained by photographing a face, the makeup image indicating a state in which makeup is applied to the face; a makeup correction unit that receives correction of the makeup image included in the generated simulation image from a user; and a correction information recording unit that records correction information which indicates a region of a post-correction makeup image using a relative position to a facial feature points.
