Blended Image Frame Generation for Fast Forward Video Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fast forward playback of digital video streams consumes significant processing resources and makes it difficult to spot short-duration events, as manual search is labor-intensive and inefficient.
Innovation Solution
A method and apparatus that merge and blend image frames to create a series of blended image frames, where each merged frame contributes to multiple blended frames, ensuring that information of interest is present across a larger number of frames, thereby enhancing visibility during fast forward playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fast forward playback is used to search through stored video data, then search speed is improved, but processing resources are heavily consumed and short-duration events become difficult to spot
Solution Approach 1:
The video stream is segmented into multiple original image frames that are then merged into fewer merged image frames. This segmentation allows the system to process and display a reduced number of frames during fast forward playback, decreasing processing resource consumption while maintaining the ability to detect events across the video timeline.
Solution Approach 2:
Information from each original image frame is copied and distributed across multiple merged image frames through the blending process. This creates ghost-like representations of events in multiple frames, ensuring that short-duration events remain detectable even when playback speed is increased, without requiring full processing of every original frame.
2Productivity
If fast forward playback is used to search through stored video data, then search speed is improved, but detection precision of short-duration events deteriorates
Solution Approach 1:
By segmenting the video into multiple original frames and merging them into fewer blended frames, the system maintains event information across multiple output frames. This segmentation strategy ensures that even brief events are captured and distributed across multiple blended frames, preserving detection precision during high-speed playback.
Solution Approach 2:
The blending process creates multiple copies of event information from each original frame across several merged frames. This copying mechanism ensures that short-duration events are not lost during fast forward playback, as their information is replicated and visible across multiple frames, thereby maintaining measurement precision.
3Use of energy by moving object
If manual search through digital video stream is used, then processing resources are conserved, but search efficiency and time consumption worsen
Solution Approach 1:
The system segments the video content into representative merged frames that capture essential information from multiple original frames. This segmentation enables automated processing of a reduced frame set, significantly reducing both processing resource usage and search time compared to manual review of all original frames.
Solution Approach 2:
By copying and distributing event information across multiple merged frames through blending, the system creates a compressed representation of the video that retains detectability of short events. This allows automated search to proceed efficiently with reduced processing load while maintaining search effectiveness.
