Visualized Image Display Device for Object Class Temporal Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to visually check the temporal change of a feature of an object in a video for each object class, as they do not organically associate the visualization of temporal changes with object classification.
Innovation Solution
A visualized image display device that acquires time-series feature data and classification data, allowing users to select a class ID for visualization, and displays a feature image representing the temporal change of the selected class ID on a display unit, enabling the visualization of temporal changes for each object class.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If time-series feature data and classification data are not organically associated, then the system structure remains simple, but it becomes difficult to visually check temporal changes of object features for each object class
Solution Approach 1:
The patent merges time-series feature data and classification data by establishing an organic association between them through object IDs. The display control means integrates both data types to generate feature images that simultaneously represent temporal changes and object classifications, allowing users to visually check temporal changes for each object class in a unified display.
Solution Approach 2:
The patent uses object IDs as an intermediary to bridge time-series feature data and classification data. The display control means utilizes this intermediary association to selectively extract and display feature data for specific object classes, enabling organized visual inspection without direct integration of the entire datasets.
2Loss of information
If all object data is visualized without classification, then the visualization process is simple, but it becomes difficult to compare temporal changes across different object classes
Solution Approach 1:
The patent segments the visualization process by object class using classification data. The display control means divides the time-series feature data according to different object IDs and their corresponding classes, generating separate feature images for each class. This segmentation enables clear comparison of temporal changes across different object classes while maintaining manageable processing through systematic division.
3Measurement precision
If classification data is integrated with time-series data, then temporal changes can be checked for each class, but the data processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing the association between classification data and time-series feature data through object IDs before the visualization process. This pre-association allows the display control means to efficiently retrieve and process only the relevant feature data for selected object classes, improving measurement precision for temporal change detection while reducing actual processing complexity during operation.

AI summary
A visualized image display device includes an acquisition means for acquiring time-series feature data in which time-series data of a feature of an object in a video and an object ID are associated with each other, and classification data in which the object ID and a class ID labeled to the object are associated with each other; a selection means for selecting a class ID to be visualized, and a display control means for acquiring the object ID associated with the selected class ID from the classification data, acquiring time-series data associated with the acquired object ID from the time-series feature data, and on the basis of the acquired time-series data, displaying a feature image representing a temporal change of the feature of the object having the selected class ID, on a display unit.
