We describe Nonnegative Double Singular Value Decomposition (NNDSVD), a new method designed to enhance the initialization stage of nonnegative matrix factorization (NMF). NNDSVD c...
Generating semantic lexicons semiautomatically could be a great time saver, relative to creating them by hand. In this paper, we present an algorithm for extracting potential entr...
We present algorithms for image-based rendering and modeling in video-endoscopy. Our algorithms are aimed at alleviating two common viewing problems in video-endoscopy: that the s...
This paper presents an image super-resolution method that enhances spatial resolution of MRI images in the slice-select direction. The algorithm employs Tikhonov regularization, us...

Condensation is a widely-used tracking algorithm based on particle filters. Although some results have been achieved, it has several unpleasant behaviours. In this paper, we highl...
