Mining for video production invariants to measure style similarity

This article focuses on video document comparison using audiovisual production invariants (API). API are characterized by invariant segments obtained on a set of low‐level features. We propose an algorithm to detect production invariants throughout a collection of audiovisual documents. The algorithm runs on low‐level features, considered as time series, and extracts invariant segments using a one‐dimensional morphological envelop comparison. Then, based on the extracted results, we define a style similarity measure between two video documents. A derivative pseudo distance is also proposed. © 2006 Wiley Periodicals, Inc.
