Overlapping Video Object Rendering for Search Summarization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video search systems are inconvenient and time-consuming for users as they require separate reproduction of multiple video sections to determine details, which can be cumbersome and inefficient.
Innovation Solution
A video search system that includes a search engine to extract video data matching a search condition and a browsing engine to generate a summarized video by rendering objects in an overlapping manner on a background model, maintaining object appearing order, and allowing three-dimensional rendering and filtering based on user requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate reproduction of multiple video sections is used, then users can determine details of video sections, but it causes inconvenience and is time-consuming
Solution Approach 1:
The patent merges multiple video sections into a single summarized video by superimposing multiple video streams at different transparency levels. This allows users to view details from multiple sections simultaneously without separate reproduction, resolving the contradiction between detail recognition accuracy and time consumption.
Solution Approach 2:
The patent introduces a temporal dimension by overlaying video sections at different time points with varying transparency. This dimensional approach allows users to perceive multiple video moments simultaneously in a unified visual space, eliminating the need for sequential separate reproduction.
2Ease of operation
If video summary is made by reducing play length, then convenient function of recognizing details is provided, but video information may be lost
Solution Approach 1:
The patent combines multiple video sections with different transparency levels to create a summarized video that maintains information completeness. By merging video streams rather than simply reducing play length, the system preserves detailed information while providing convenient single-video access.
Solution Approach 2:
The patent uses transparency as an intermediary mechanism to balance information completeness and convenience. Different video sections are overlaid at varying transparency levels, allowing users to access detailed information without requiring complete video reproduction, thus preventing information loss while maintaining ease of operation.
3Adaptability or versatility
If multiple objects are rendered in overlapping manner, then search result visualization is improved, but rendering complexity increases
Solution Approach 1:
The patent implements dynamic rendering by adjusting transparency levels of overlaid video sections based on search results. This dynamic approach allows the system to visualize multiple objects in overlapping manners while managing rendering complexity through algorithmic control of visual properties.
Solution Approach 2:
The patent changes the transparency parameter of video sections to achieve overlapping rendering of multiple objects. By adjusting this single key parameter rather than implementing complex rendering pipelines, the system improves visualization capability while controlling rendering process complexity.
