Spread spectrum-based watermarking for Tardos code-based fingerprinting for H.264/AVC video
In this paper, we present a novel approach for active fingerprinting of state of the art video codec H.264/AVC. Tardos probabilistic fingerprinting code is embedded in H.264/AVC v...

Phase Field Models and Higher-Order Active Contours
The representation and modelling of regions is an important topic in computer vision. In this paper, we represent a region via a level set of a ‘phase field’ function. The fu...

Finsler Active Contours
In this paper, we propose an image segmentation technique based on augmenting the conformal (or geodesic) active contour framework with directional information. In the isotropic ca...

Active Learning of Hyperspectral Data with Spatially Dependent Label Acquisition Costs
Supervised learners can be used to automatically classify many types of spatially distributed data. For example, land cover classification by hyperspectral image data analysis is ...
