Two-Step Detection of Video Shot Boundaries in a Wavelet Transform Domain

Abstract

This paper presents a two-step algorithm for detecting video shot boundaries in a wavelet transform domain. It captures gradual shot transitions such as dissolves and fades as well as abrupt shot transitions such as cuts. At the first step, it computes a distance between video intervals to find an isolated interval. Then, at the second step, it computes a distance between frames to specify the exact location of a shot boundary. Its effectiveness is evaluated in terms of recall and precision.
