Video Retrieval Using Global Features in Keyframes.

Abstract

We describe our experiments for the shot-boundary detection and search tasks for the TREC-11 video track. Our shot-boundary detection scheme is based on a multi-timescale detection algorithm in which colour histogram dierences are examined over a range of frames. Our search eorts are based on a system which brings together a number of global features encompassing colour, texture and text features derived from speech recognition transcripts into a unique relevance feedback system.
