IRIT @ TRECVid 2010: Hidden Markov Models for Context-aware Late Fusion of Multiple Audio Classifiers

By Hervé Bredin, Lionel Koenig and Jérôme Farinas


This notebook paper describes the four runs submitted by IRIT at TRECVid 2010 Semantic Indexing task. The four submitted runs can be described and compared as follows: • Run 4 – late fusion (weighted sum) of multiple audio-only classifiers output • Run 3 – context-aware re-rank of run 4 using hidden Markov model • Run 2 – context-aware late fusion of multiple audio classifiers output with hidden Markov model • Run 1 – late fusion (weighted sum) of multiple audio & video classifiers output
