Unified Object Image Registration for Multi-Function Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses require users to perform different registration operations for various subject detection and recognition functions, placing a heavy burden on the user as the operations differ between functions.
Innovation Solution
An image processing apparatus with a unified object registration operation method that includes a designation unit for selecting an object image, detection units for identifying subjects, and storage units for feature extraction and storage, allowing for common registration across multiple subject detection and recognition functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different registration operations are used for various subject detection and recognition functions, then each function can be optimized for its specific purpose, but the user burden increases and ease of operation deteriorates
Solution Approach 1:
The patent implements a unified registration operation that serves multiple subject detection and recognition functions simultaneously. The single registration process extracts features that can be used across different functions (face detection, person recognition, object tracking), eliminating the need for separate registration operations for each function while maintaining function-specific optimization through selective feature usage.
2Reliability
If multiple separate registration operations are implemented for different functions, then each function receives dedicated optimization, but the device complexity and number of operations increase
Solution Approach 1:
The patent merges multiple registration operations into a single unified process. The registration operation simultaneously performs feature extraction that benefits multiple functions (face features, person identification features, object tracking features), reducing the number of separate operations from multiple to one while maintaining the detection precision required by each function through multi-purpose feature extraction.
3Ease of operation
If a unified registration operation is used for multiple functions, then ease of operation improves and user burden decreases, but the ability to optimize for specific functions may be reduced
Solution Approach 1:
The patent uses parameter changes to enable a unified registration operation to serve multiple functions. The system extracts multiple types of features (face geometry, skin tone, person ID, object characteristics) from a single registration, and dynamically selects or weights appropriate features based on the specific function being performed, thus maintaining function-specific optimization while using a unified registration process.

AI summary
An image processing apparatus comprising: a first detection unit adapted to detect a first subject from an object image; a first extraction unit adapted to extract a first feature amount for identifying an attribute of the first subject; a second extraction unit adapted to extract a second feature amount for detecting the second subject; a first storage unit adapted to store the first feature amount; and a second storage unit adapted to store the second feature amount, wherein when the first detection unit detects the first subject, the first extraction unit extracts the first feature amount and the first storage unit stores the amount, and when the first detection unit cannot detect the first subject, the second extraction unit extracts the second feature amount and the second storage unit stores the amount.
