Avatar Update via Excluded Image Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating avatars from user images often include unnecessary information that users wish to exclude, such as changes in hairstyle or clothing below the neck.
Innovation Solution
An information processing apparatus and method that acquires a new user image, generates an excluded image by removing unwanted portions, and updates the avatar by rendering the excluded image in overlap with the original image, ensuring that unnecessary information is not reflected in the avatar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a new user image is used to update the avatar, then the avatar reflects current appearance, but unnecessary information (hairstyle changes, clothing below neck) is also reflected
Solution Approach 1:
The patent segments the user image into multiple regions of interest (face, head, neck) and excludes specific regions (hairstyle, clothing below neck) from avatar generation. This allows selective inclusion of desired appearance features while excluding unwanted ones, resolving the contradiction between reflecting current appearance and filtering unnecessary information.
Solution Approach 2:
The patent extracts and removes specific portions of the user image that contain unnecessary information (hairstyle changes, clothing below the neck) before generating the avatar. This extraction process ensures that only the desired appearance features are reflected in the updated avatar, while unwanted information is completely excluded.
2Productivity
If the entire new image is rendered onto the avatar, then all appearance changes are captured, but privacy and user control are compromised
Solution Approach 1:
The patent implements a dynamic region-of-interest selection mechanism that allows the avatar generation system to adaptively determine which portions of the user image should be included or excluded. This dynamic control enables users to specify their preferences for appearance updates while maintaining efficient automated processing, balancing productivity and user control.
3Reliability
If multiple images are processed to update the avatar, then comprehensive appearance information is obtained, but processing complexity increases
Solution Approach 1:
The patent performs preliminary processing of multiple user images by identifying and extracting regions of interest before the actual avatar generation. This preliminary segmentation and region extraction simplifies subsequent processing steps, allowing the system to handle multiple images efficiently while maintaining comprehensive appearance data for reliable avatar updates.

AI summary
An information processing apparatus includes a controller configured to generate an avatar of a user as a 3D object based on a user image of the user. The controller is configured to acquire a new image of the user, generate an excluded image by excluding a portion from the new image, and update the avatar of the user by rendering the excluded image in overlap with at least a portion of the user image.
