Noise-contrastive estimation: A new estimation principle for unnormalized statistical models
We present a new estimation principle for parameterized statistical models. The idea is to perform nonlinear logistic regression to discriminate between the observed data and some...

Noise-Contrastive Estimation of Unnormalized Statistical Models, with Applications to Natural Image Statistics
We consider the task of estimating, from observed data, a probabilistic model that is parameterized by a finite number of parameters. In particular, we are considering the situat...

A 3D discrete curvelet based method for segmenting dynamic textures
This paper presents a new approach for segmenting a video sequence containing dynamic textures. The proposed method is based on a 2D+T curvelet transform and an octree hierarchica...

Embedded wavelet region-based coding methods applied to digital mammography
In this paper, we investigate region-based embedded wavelet compression methods and introduce region-based extensions of the Set Partitioning In Hierarchical Trees (SPIHT) and the...
