Seminario di Informatica: 3D Shape matching by bag-of-feature descriptors

Giovedì 30 Ottobre 2014, ore 11:30 - Aula 2AB40 - Umberto Castellani



Giovedì 30 Ottobre 2014 alle ore 11:30 in aula 2AB40, Umberto Castellani (Università di Verona) terrà un seminario dal titolo "3D Shape matching by bag-of-feature descriptors".

3D shape matching is very important in a wide variety of fields such as computer graphics, computer vision, and medical image analysis with applications like object recognition, automatic medical diagnosis, and content-based shape retrieval. Recent methods are based on the so called Bag-of-Features (BoF) paradigm commonly used in text and image retrieval by first computing local shape descriptors, and then representing each shape in a ‘geometric dictionary’ using vector quantization. In this talk the matching approach based on the BoF framework will be introduced by proposing several variants and advanced aspects of the involved pipeline (i.e., supervised and non-supervised). Finally, some case studies will be reported
for 3D shape retrieval and shape-based medical image classification.
