Background Models for Tracking Objects in Water

Ablavsky, V. Proceedings of IEEE International Conference on Image Processing, Barcelona, Spain (September 2006) This paper presents a novel background analysis technique to enable robust tracking of objects in water-based scenarios. Current pixel-wise statistical background models support automatic change detection in many outdoor situations, but are limited to background changes which can be modeled via a […]

Automatic Feature Selection with Applications to Script Identification of Degraded Documents

Ablavsky, V. and Stevens, M. R. Proceedings of the Seventh International Conference on Document Analysis and Recognition, Edinburgh, Scotland (August 2003) Current approaches to script identification rely on hand-selected features and often require processing a significant part of the document to achieve reliable identification. We present an approach that applies a large pool of image features […]
