Interactive Image Cloud Visualization for Video Content Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigating and understanding video content is challenging due to the sheer amount of visual content, temporal changes, and repetitive elements, making it difficult for users to grasp the video's content without adequate representation, as single images or multiple thumbnails may be misleading or redundant, and summary animations lack control and granularity.
Innovation Solution
A processor generates interactive image clouds based on videos, including a representative image and associated images, allowing users to browse and understand visual content and temporal changes, with expansion animations providing deeper inspection and a cloud structure for visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single image or multiple thumbnails are used to represent video content, then the device complexity is reduced, but the information completeness deteriorates leading to misleading or redundant representation
Solution Approach 1:
The video content is segmented into multiple keyframes that are then clustered into groups representing different scenes or segments. Each image cloud contains a representative image and multiple associated images, creating a hierarchical segmentation that preserves information while maintaining manageable complexity.
Solution Approach 2:
The patent implements a nested structure where image clouds are nested within video representations, and associated images are nested within each image cloud. This nested organization allows comprehensive video content representation through multiple layers of detail without linearly increasing device complexity.
2Loss of information
If multiple thumbnails are used to represent video content, then the information completeness is improved, but the ease of operation deteriorates due to redundancy and difficulty in navigation
Solution Approach 1:
Multiple thumbnails are merged into a single image cloud visualization that preserves all essential information. The cloud structure combines multiple associated images around a representative image, allowing users to navigate a single interactive element that contains comprehensive video content representation without the clutter of multiple separate thumbnails.
Solution Approach 2:
The image cloud is designed as a dynamic interactive element that responds to user actions. Users can hover over, click, or interact with the cloud to expand or collapse associated images, allowing the representation to adapt to user needs and providing easy navigation through animated transitions rather than static multiple thumbnails.
3Loss of information
If summary animations are used to represent videos, then the information completeness is improved, but the ease of operation deteriorates due to lack of user control and granularity
Solution Approach 1:
The patent replaces automatic summary animations with a dynamic, user-controlled image cloud system. Users can interact with the cloud at their own pace, expanding and collapsing associated images to reveal or hide detailed content. This provides both comprehensive information representation and full user control over the level of detail displayed, eliminating the forced pacing of animations.
