research overview |
Alexei was a a full-time PhD student in information retrieval at the
Department of Computing, Imperial College London, in the Multimedia and
Information Systems Group, supervised by Prof Stefan Rueger.
His thesis http://people.kmi.open.ac.uk/stefan/www-pub/a.yavlinsky-phd.pdf Image
indexing and retrieval using automated annotation, published in 2007,
argues that models of simple image features, such as global colour and
texture, can be used to predict instances of different objects and scenes
within photographic images. On this basis Alexei proposed the use of
nonparametric density estimation to model these features and thus endow
unlabelled images with probabilities of containing particular objects and
scenes. This process, termed automated image annotation, enables one to
set up a scalable image indexing framework that allows users to retrieve
unlabelled images from large collections using simple keyword queries. |
