Image Synchronization Unit for Multi-Dancer Video Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to synchronize the movements of multiple dancers with music in videos, especially when the lead dancer's movements are not perfectly synchronized with the music, leading to unnatural movements of other dancers.
Innovation Solution
A program and image processing apparatus that includes an image synchronization unit, which generates an image of a second person dancing in synchronization with a first person by analyzing the movements of the first person in relation to the music and applying those synchronizations to the second person's image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the movement of the dancer as the teacher is assumed to be correct and used as the basis for synchronization, then the encoding and synthesis process is simplified, but the synchronization accuracy deteriorates when the teacher's movement is not appropriately synchronized with the music
Solution Approach 1:
The patent introduces an intermediary process that analyzes both the teacher's movement and music independently, then uses their temporal correspondence as a mediator to establish accurate synchronization timing. This intermediary analysis layer resolves the contradiction by not blindly trusting the teacher's movement assumption while still utilizing it as a reference, thereby maintaining process simplicity without sacrificing accuracy.
2Adaptability or versatility
If encoded information of multiple other dancers is synthesized to synchronize their movements, then the number of dancers that can be synchronized increases, but the naturalness of movement deteriorates when there is a plurality of other dancers
Solution Approach 1:
The patent applies local quality by selectively processing each dancer's encoded information based on their individual characteristics and synchronization requirements. Rather than uniformly synthesizing all dancers' data, the system adjusts the synthesis process for each dancer locally, preserving the naturalness of their specific movements while still achieving multi-dancer synchronization. This selective, differentiated approach resolves the contradiction between handling multiple dancers and maintaining movement naturalness.

AI summary
The present disclosure relates to a program, an image processing apparatus, and an image processing method capable of appropriately synchronizing movements of a plurality of dancers with music in a video in which the plurality of dancers dances. In a video in which a plurality of dancers dances, an action of a main dancer is synchronized with music, and the action of the main dancer synchronized with the music is synchronized with an operation of a sub-dancer, so that an image in which the sub-dancer is synchronized with the action of the main dancer is generated. This can be applied to video editing software.
