Image Processing Apparatus Candidate Selection for Facial Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in recognizing objects within images, especially in crowded scenes or with poor capturing conditions, such as small or non-frontal facial images, making it challenging to accurately identify individuals using existing facial recognition technologies in consumer-grade cameras.
Innovation Solution
An image processing apparatus that detects selection candidate images, such as facial images, and overlays them as a candidate presentation list on the main image, allowing users to easily select and emphasize the target object for focus, using a CPU or DSP for processing and a display unit for visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual identification technology is applied to track specific persons, then the ability to identify individuals is improved, but the processing ability requirement becomes excessively high for consumer appliances
Solution Approach 1:
The patent segments the complex individual identification task into simpler components: detecting facial images, extracting candidate regions, and displaying them in a list. This breakdown reduces the processing burden on consumer-grade devices while maintaining identification capability.
Solution Approach 2:
The patent introduces an intermediary display list that shows detected facial images and their positions. This intermediary representation allows users to identify targets without requiring the system to perform complex real-time individual identification, thus reducing processing requirements.
2Adaptability or versatility
If facial recognition is performed under various capturing conditions, then the适用范围 is improved, but the identification accuracy deteriorates due to small images, shielding, shadows, and non-frontal faces
Solution Approach 1:
The patent performs partial facial recognition by detecting only sufficient features to identify candidate regions and display them in a list. It does not attempt full individual identification under all conditions, thereby maintaining acceptable accuracy while adapting to various capturing conditions including small images and non-frontal faces.
3Area of stationary object
If the entire image is displayed without assistance, then the complete scene is visible, but the user cannot quickly recognize specific objects to focus on
Solution Approach 1:
The patent segments the display into two parts: the main image showing the complete scene and a separate candidate list showing detected facial images with position information. This segmentation allows users to see both the overall scene and specific targets of interest simultaneously.
Solution Approach 2:
The patent creates a copy of the detected facial images and their position information in a separate display list. This copy provides additional information about where to look in the main image without obscuring the original scene, making it easier for users to locate specific objects.

AI summary
An information processing apparatus may include a control device. The control device may generate display data including a main image for display in a first area of a display area and a list of candidate images for display in a second area of the display area at a same time the main image is displayed in the first area, wherein the candidate images are extracted from and represent respective objects in the main image. Also, the control device may receive an input from a user to select one candidate image from the list, wherein the display data is generated based on selection of the one candidate image.
