Style similarity measure for video documents comparison

We define a style similarity measure for video documents based on the localization of common elements and on the temporal order in which they appear in each document. Common elements for a couple of compared videos are segments presenting similar behaviors on a subset of low or mid level features extracted for the comparison process. We propose a method to compare two video documents and to extract those similar elements using dynamic programming and one-dimensional morphological operations. The similarity measure is applied on TV-news broadcast to illustrate its behavior.
