Video Chip Array for Efficient Feature Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video analysis methods are time-consuming and prone to human error due to manual playback and frame-by-frame analysis, making them inefficient for large-scale video surveillance data processing across various applications.
Innovation Solution
Implementing a system that automatically identifies features in video streams, generates video chips, and displays them in a graphical user interface for concurrent playback, allowing for efficient temporal and spatial analysis with minimal user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual video playback and frame-by-frame analysis are used, then detailed feature inspection is possible, but analysis time and cost increase significantly
Solution Approach 1:
The patent segments video streams into multiple synchronized video chips that can be displayed and analyzed simultaneously. Each video chip represents a temporal segment of the video stream, allowing analysts to view multiple segments at once rather than sequentially, thereby reducing analysis time while maintaining inspection accuracy
Solution Approach 2:
The patent adds a spatial dimension to video analysis by displaying multiple video chips in a two-dimensional grid layout. This allows simultaneous visualization of multiple temporal segments across different spatial locations on the screen, enabling parallel analysis without sacrificing detail inspection capability
2Productivity
If multiple video streams are compared by toggling or side-by-side viewing, then comprehensive analysis is achieved, but operator fatigue and human error increase
Solution Approach 1:
The patent merges multiple video streams and their temporal segments into a single unified graphical interface displaying an array of video chips. This consolidation allows comprehensive comparison of multiple streams without requiring operators to toggle between separate windows or screens, reducing fatigue and improving reliability
Solution Approach 2:
The video chip array interface serves multiple functions simultaneously: it displays multiple video streams, provides temporal segmentation, enables spatial comparison, and allows synchronized playback control. This multi-functionality consolidates what would otherwise require multiple separate tools into a single system
3Measurement precision
If traditional video analysis methods are used, then detailed examination is possible, but processing efficiency for large-scale data decreases
Solution Approach 1:
The system performs preliminary automatic feature detection and video chip generation before the analysis phase. Video chips are pre-segmented and prepared with identified features, so when analysts review the chips, the detailed examination can focus on pre-processed content, improving both efficiency and accuracy
