Abstract

A method and a system for deriving visual rhythm from a video signal are described. A feature extraction module receives the video signal and extracts a two-dimensional feature from the video signal. A one-dimensional video feature computation module derives a one-dimensional feature from the extracted two-dimensional feature. A visual rhythm detector module detects a visual beat and a visual tempo from the one-dimensional feature.
