Quality Measures for Interactive Image Retrieval with a Performance Evaluation of Two 3x3 Texel-based Methods

The aim of the Leiden Imaging and Multi-media Group in collaboration with Philips is to develop and evaluate content-based indexing and interactive retrieval methods for large photo collections and to integrate them with annotation based methods. Ground-truth is provided by copy pairs in the Leiden Portrait Database, a database of scanned-in images of 19th-century Dutch studio portraits (“Cartes de Visite” ).
