User interaction and performance evaluation in content-based visual information retrieval

MULLER, Henning

Abstract

Cette thèse donne une vue détaillée sur la recherche d'informations visuelles basée sur le contenu, un secteur d'étude actif dans le domaine de la vision par ordinateur. Les principaux objectifs de cette investigation sont la recherche d'images ou d'autres documents visuels dans les archives, basée sur le contenu visuel uniquement, et, en général, sans l'usage d'annotations textuelles. Les deux thèmes principaux sont l'interaction avec l'utilisateur et l'évaluation de performance. L'interaction avec l'utilisateur, et l'apprentissage à long terme en particulier, s'est révélée être la clé pour obtenir de bonnes performances. L'interaction de différentes méthodes améliore les résultats des recherches de manière significative.

L'évaluation des résultats de recherche a été largement négligée dans la recherche. Ceci est pourtant extrêmement important puisque seule une évaluation correcte permet de montrer les progrès que certaines techniques peuvent apporter. Un benchmark complètement automatisé et basé sur des tests effectués par de vrais utilisateurs est mis en oeuvre sur la base de langage de communication MRML.
