Video Slide Extraction for Fast Visual Summaries and Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing prevalence of videos and online meetings leads to information overload, time constraints, attention span issues, retention challenges, and difficulty in locating specific information, making it hard for viewers to efficiently extract key information and assess comprehension.
Innovation Solution
A video summarization system that automatically identifies and captures slides, slide markups, dynamic information-rich visual images, and participant interactions, generating concise visual summaries with associated comments and links, enabling efficient summarization, storage, search, and sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users watch entire videos to extract key information, then comprehensive understanding is achieved, but time consumption increases significantly
Solution Approach 1:
The system extracts key information, slides, and important visual elements from videos to create condensed summaries. This allows users to obtain comprehensive understanding without watching entire videos, directly resolving the contradiction between information completeness and time efficiency
Solution Approach 2:
The video content is segmented into discrete slides and key information units that can be independently reviewed. This segmentation enables users to efficiently extract essential information without processing the entire continuous video stream, reducing time consumption while maintaining understanding
2Measurement precision
If users manually review video content to locate specific information, then accurate information is found, but search efficiency decreases
Solution Approach 1:
The system performs preliminary analysis of video content to identify and organize key information, slides, and important segments before user search. This pre-processing enables rapid and accurate location of specific information, simultaneously improving search efficiency and information accuracy
Solution Approach 2:
The system introduces an intermediary indexing structure that maps video content to searchable keywords and concepts. This intermediary layer enables efficient retrieval of specific information while maintaining accuracy, resolving the contradiction between manual review thoroughness and search speed
3Loss of information
If detailed video content is presented to ensure thorough comprehension, then understanding depth increases, but user attention and engagement decrease
Solution Approach 1:
Video content is divided into discrete, manageable slides and key information units. This segmentation allows users to engage with content in smaller, more digestible portions while maintaining understanding depth, resolving the contradiction between thorough comprehension and user engagement
Solution Approach 2:
The system dynamically adapts the level of detail presented based on user interaction and needs. Users can access detailed information when needed while defaulting to condensed summaries for general understanding, maintaining both comprehension depth and engagement
Data Source
AI summary
generally comprises obtaining one or more images from the video as the video is played, locating a presence of a shape or text from each of the one or more images, determining whether the shape or text corresponds to a prior shape or text from a prior base image, determining whether each of the one or more images comprises a corresponding slide, presenting the one or more images as one or more slides upon an interface displayed to a user, providing a timestamp upon each of the one or more slides, whereby selection of the timestamp by the user plays the video at a location which correlates to the timestamp within the video, and presenting the one or more slides including the timestamp to the user.
