Real-Time Video Makeup Simulation with Illumination Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional process of selling cosmetics is cumbersome for both retailers and customers, as it involves physically applying and removing samples, limiting the number of products that can be tried on, and existing digital simulation methods fail to account for variations in illumination and position, especially in real-time video-based simulations.
Innovation Solution
A computer-implemented method using a personal computational device to capture real-time images, apply desired makeup looks, and generate composite images, adapting to illumination and position variations, allowing for real-time video-based makeup simulation and retail ordering of physical or virtual cosmetic products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical samples and dedicated staff are used to apply cosmetics to customers, then customers can assess the feel and look of cosmetics, but the process becomes cumbersome and time-consuming for both retailers and customers
Solution Approach 1:
The patent uses digital image processing to create a virtual copy of the customer's face and applies digital representations of cosmetic products to this copy. This allows customers to try on multiple makeup looks instantly without physical application, eliminating the time-consuming process while maintaining visual assessment accuracy.
Solution Approach 2:
The patent replaces the mechanical process of physical sample application with an automated image processing system. The system captures real-time video images, processes them through algorithms to detect facial features and skin properties, and digitally overlays cosmetic effects, substituting manual staff application with automated computational methods.
2Ease of manufacture
If image-based methods are used for digital makeup simulation, then offline makeup application is possible, but transparency properties of makeup and local illumination variations are not accounted for
Solution Approach 1:
The patent transitions from static image-based methods to dynamic real-time video-based simulation. The system continuously captures video frames and dynamically adjusts makeup application based on changing lighting conditions, head movements, and facial expressions, maintaining accuracy throughout the simulation process.
Solution Approach 2:
The patent analyzes and adapts to variations in illumination parameters by detecting local lighting conditions on different parts of the face and adjusting the digital makeup application accordingly. The system modifies parameters such as brightness, contrast, and color balance to match the actual lighting environment and preserve the transparent properties of cosmetic products.
3Adaptability or versatility
If real-time video-based simulation is implemented, then adaptive makeup application to position and orientation variations is achieved, but computational complexity increases
Solution Approach 1:
The patent divides the facial image into multiple regions or segments corresponding to different facial features and zones. This segmentation allows the system to process and apply makeup to specific areas independently, reducing overall computational complexity while maintaining adaptability to local variations in position and illumination.
Data Source
AI summary
Computer-implemented methods for vending at least one cosmetic product to a first consumer. A real-time image of a portion of a body of the consumer is captured using a personal computational device and the consumer provides a desired makeup look via the personal computational device. The desired makeup look is then applied to an image of the portion of the body of the consumer, thereby generating a composite image of the portion of the body of the first consumer with the desired makeup look, and a retail order for the cosmetic product is received from the consumer. The order may be received before or after the consumer's image is captured. Another consumer, or a product specialist, may be involved in the aforesaid process via a computer communications link.
