Dynamic Semantic Annotation for Moving Objects in Interactive Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video annotation systems provide static and unidirectional annotations, limiting user interaction and the ability to add or receive additional information, especially for moving objects in videos, requiring users to exit the video screen for further actions.
Innovation Solution
A system with an intuitive interface for creating and sharing semantic annotations on moving objects in videos, allowing users to select, annotate, and track objects, overlay annotation information on video frames, and share annotated videos, enabling interactive and dynamic annotation experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional static annotation is used, then annotation creation is simple, but user interaction capability is limited
Solution Approach 1:
The patent transforms static annotation into dynamic annotation by enabling annotations to move and change position automatically according to object movement in video frames. The annotation system now dynamically tracks moving objects and adjusts annotation positions in real-time, resolving the contradiction between operational simplicity and interaction capability.
Solution Approach 2:
The system implements feedback mechanisms where annotation positions are automatically adjusted based on object detection results from successive video frames. This feedback loop enables the annotation to respond to object movement, enhancing user interaction while maintaining simple annotation creation processes.
2Ease of manufacture
If static annotation is used, then annotation information is easy to provide, but additional information cannot be added or received
Solution Approach 1:
The patent introduces an intermediary annotation system that acts as a bridge between video content and user interaction. This intermediary enables bidirectional information exchange by allowing users to add, modify, and share annotation information while maintaining the original annotation structure, thus preventing information loss.
Solution Approach 2:
The annotation system is designed to perform multiple functions: displaying original annotations, tracking moving objects, enabling user interactions, and facilitating information sharing. This multi-functionality allows the system to maintain ease of information provision while enabling comprehensive additional information exchange.
3Device complexity
If simple text link annotation is used, then annotation creation is straightforward, but user interaction is limited to watching
Solution Approach 1:
The patent transforms static text link annotations into dynamic annotations that automatically track and follow moving objects throughout video playback. This dynamic behavior enhances user interaction by maintaining contextual relevance without increasing annotation structural complexity.
Solution Approach 2:
The annotation system performs self-service by automatically updating annotation positions and content based on object detection results, eliminating the need for manual adjustment and enabling seamless user interaction without complicating the annotation creation process.
4Productivity
If conventional annotation is used, then video playback is simple, but users must exit screen for additional actions
Solution Approach 1:
The patent merges annotation interaction capabilities directly into the video playback interface. Users can create, modify, and interact with annotations without leaving the video screen, combining what were previously separate actions into a unified workflow that improves productivity and eliminates time loss.
Solution Approach 2:
The video playback system is enhanced with multi-functionality to simultaneously support video display, annotation creation, annotation tracking, and user interaction. This integration allows users to perform multiple actions within the same interface without exiting the screen.
Data Source
AI summary
A system and method for making a semantic annotation for a moving object in an interactive video and an interface for the system is described. The annotation creating system may include an annotation creating unit adapted to create annotation information on a moving object contained in a video, and an annotation replaying unit adapted to execute a preview of the annotation information by the video frame or shot. The video and the annotation information may be registered in a platform for sharing the video.
