Dynamic Makeup Deformation for Facial Movement Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional makeup simulation technologies fail to accurately depict how makeup appears when face parts move, such as eyes opening and closing, resulting in unnatural simulations.
Innovation Solution
A makeup simulation device that acquires and processes face images before and after facial movements, deforms makeup parts accordingly, and superimposes these deformed parts onto the moving face images to create a natural appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional makeup simulation superimposes makeup parts onto still images, then the makeup simulation is simple to implement, but the simulation does not reflect how makeup appears when face parts move
Solution Approach 1:
The patent applies dynamics by transitioning from static image superposition to dynamic deformation of makeup parts. The system deforms makeup parts according to facial movements (eye opening/closing, eyebrow raising) by calculating deformation amounts based on coordinate changes between reference images and target images, making the simulation dynamic and movement-responsive
Solution Approach 2:
The patent uses copying by creating a reference image with pre-applied makeup parts, then copying and deforming these makeup parts onto target images. The makeup parts are extracted from the reference image and reapplied to multiple target images showing different facial expressions, enabling consistent yet adaptive makeup simulation across movements
2Adaptability or versatility
If makeup parts are fixed on still images, then the processing is computationally simple, but the makeup appearance does not change with facial movements
Solution Approach 1:
The patent applies preliminary action by preparing a reference image with makeup parts applied in advance. This reference image serves as a template from which makeup parts are extracted and then deformed for various facial expressions. The preprocessing of the reference image enables faster processing when generating simulations for multiple target images
Solution Approach 2:
The patent implements parameter changes by modifying the coordinates and shapes of makeup parts based on facial movement parameters. The system calculates deformation amounts by comparing coordinate changes between reference and target images, then applies these parameter transformations to adapt the makeup appearance to different facial expressions

AI summary
A makeup simulation device that superimposes a makeup part onto a face image obtained by photographing a face of a person and causes the face image to be displayed on a display device includes: a face image acquisition unit that acquires a first face image and a second face image that are different from each other in appearance of the face due to movement of a specific face part; a makeup part drawing unit that draws a makeup part on the specific face part in the first face image; a makeup part deforming unit that deforms the makeup part drawn on the specific face part of the first face image in accordance with movement of the specific face part; and a makeup part superimposing unit that superimposes the deformed makeup part onto the second face image.
