Authentication Data Generation for Multi-Angle Face Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face authentication systems face challenges in maintaining high authentication accuracy due to limitations in handling face direction variations, which lead to increased processing loads and reduced accuracy when capturing images from different angles.
Innovation Solution
An information processing apparatus that generates and reflects updated authentication data across multiple image capturing devices, allowing for the inclusion of feature amounts corresponding to various capturing conditions, including face directions different from the initial registration, thereby expanding the authentication data to improve accuracy.

Engineering Contradiction Analysis
1Measurement precision
If face direction variation of authentication data is increased to perform face authentication with high accuracy, then authentication accuracy is improved, but the load of comparing processing becomes high
Solution Approach 1:
The system performs preliminary action by pre-generating authentication data for multiple face directions (0°, 30°, 60°, 90°, etc.) and storing them in advance in the authentication database. When authentication is needed, the system only needs to compare the captured face image against these pre-generated direction-specific authentication data, avoiding the need for real-time generation and reducing processing load during actual authentication operations.
2Productivity
If only feature amount of face image that has been successfully authenticated is transmitted to another apparatus, then data transmission efficiency is improved, but improvement of authentication accuracy is limited
Solution Approach 1:
The system applies parameter changes by transforming authentication data into different face direction parameters (0°, 30°, 60°, 90°, etc.) and transmitting these direction-specific feature amounts to other apparatuses. This allows receiving apparatuses to authenticate faces captured at various angles by comparing against the transmitted direction-matched authentication data, thereby improving authentication accuracy across different capturing conditions while maintaining efficient data transmission.

AI summary
An information processing apparatus generates authentication data that can be used for authentication of a first object that is included in a captured image captured by a first image capturing apparatus and has been authenticated by a first authentication apparatus corresponding to the first image capturing apparatus; and causes the authentication data to be reflected to an authentication database (DB) of at least one authentication apparatus included in a plurality of authentication apparatuses. The apparatus generates second authentication data corresponding to a second capturing condition differing from a first capturing condition corresponding to first authentication data that is included in the authentication DB of the first authentication apparatus and was used when authenticating the first object.
