1. Introduction

We present how to extract rhythm information in dance videos and music signals, and accordingly correlate two media based on this novel representation. From danceríŽs movement, we construct motion trajectories, detect turnings and stops of trajectories, and then estimate rhythm of motion (ROM). For a music signal, music beats are extracted based on integration of audio dynamics in different frequency bands. Two modalities are therefore represented by sequences of rhythm information to facilitate determination of cross-media correspondence. Two applications are developed to show the feasibility of utilizing cross-media correspondence íV background music replacement and music video generation. In the experiments, we evaluate performance of ROM extraction, and conduct subjective/objective evaluation to show that rich experience can be obtained by the proposed applications. We also suggest that rhythm information may be used in more multimedia content applications, such as rhythm-based multimedia retrieval.
