Search Apparatus Using Key Frame Pose and Time Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques face challenges in improving search accuracy for moving images that exhibit human body movements similar to those in a query image, as they do not effectively utilize key frames and time intervals to match poses and movements.
Innovation Solution
A search apparatus and method that extracts key frames from a query moving image and searches for similar moving images based on the pose of a human body within these key frames and the time intervals between them, ensuring relevance and temporal similarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If key frames are extracted and time intervals are considered for searching similar moving images, then search accuracy for movements is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by extracting key frames at specific time intervals from the query moving image rather than processing the entire video continuously. This divides the search process into discrete temporal segments, improving measurement precision for movement similarity while managing system complexity through selective frame processing
Solution Approach 2:
The patent implements preliminary action by pre-extracting key frames and calculating their time intervals before performing the similarity search. This preparatory step establishes a temporal framework in advance, enabling more accurate movement comparison without adding complexity during the actual search execution
2Measurement precision
If multiple key frames are extracted from query moving image, then pose similarity matching is improved, but loss of time increases
Solution Approach 1:
The patent applies periodic action by extracting key frames at regular time intervals from the query moving image. This periodic sampling captures essential pose information across different time points, improving pose similarity matching accuracy while controlling processing time through systematic interval-based selection rather than continuous analysis
