Face and Body Region Authentication for Obscured Faces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in accurately authenticating individuals over an extended period when facial feature information cannot be acquired, necessitating the use of alternative body features and clothing for authentication.
Innovation Solution
An image processing device and method that includes face detection, body detection, face collation, correspondence relationship identification, and image recording, allowing for the recording of body image information when it satisfies specific conditions, even if facial features are not recognizable, to enhance authentication accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face collation processing is performed using only facial feature information, then authentication accuracy is high, but authentication cannot be performed when facial features are obscured or unrecognizable
Solution Approach 1:
The system performs both face collation processing and body collation processing, making the authentication system multi-functional. When facial features are available, face collation is performed; when obscured or unrecognizable, body collation serves as an alternative, ensuring authentication availability across different scenarios while maintaining high accuracy
Solution Approach 2:
Body image information acts as an intermediary when face collation cannot be performed. The system captures and processes body region images as a substitute when facial features are unavailable, enabling continuous authentication functionality without completely losing authentication capability
2Adaptability or versatility
If body image information is recorded for all persons, then authentication can be performed when facial features are obscured, but data storage requirements and processing complexity increase
Solution Approach 1:
The system performs body collation processing selectively rather than universally. Body image information is recorded and processed only when face collation cannot be performed or when facial features are obscured, avoiding unnecessary processing complexity while maintaining authentication availability when needed
Solution Approach 2:
The authentication system is segmented into separate face collation and body collation processing paths. This segmentation allows the system to choose the appropriate processing path based on whether facial features are available, reducing overall processing complexity by avoiding unnecessary body image processing when face collation succeeds

AI summary
A face region of a person appearing in an image is detected, a body region of the person appearing in the image is detected; face collation processing is performed using image information of the face region, a correspondence relationship between the image information of the face region and the image information of the body region is identified when the image information of the face region and the image information of the body region satisfy a predetermined correspondence relationship, and the image information of the body region is recorded when the image information of the body region of the person identified as a result of the face collation processing satisfies a recording condition.
