TLDR
We introduce a hyperspectral denoising algorithm based on spatio-spectral total variation based on SSTV regularization. Expand
Fast group sparse classification
  • A. Majumdar, R. Ward
  • Mathematics
  • Canadian Journal of Electrical and Computer…
  • 23 October 2009
TLDR
A recent work proposed a novel Group Sparse Classifier (GSC) that was based on the assumption that the training samples of a particular class approximately form a linear basis for any test sample belonging to that class. Expand
Classification via group sparsity promoting regularization

  • Mathematics, Computer Science
  • IEEE International Conference on Acoustics…
  • 19 April 2009
TLDR
We propose two alternate regularization methods, Elastic Net and Sum-Over-l2-norm. Expand
Face Recognition by Curvelet Based Feature Extraction
TLDR
This paper proposes a new method for face recognition based on a multiresolution analysis tool called Digital Curvelet Transform. Expand
Detecting Silicone Mask-Based Presentation Attack via Deep Dictionary Learning
TLDR
In movies, film stars portray another identity or obfuscate their identity with the help of silicone/latex masks. Expand
Compressed sensing of color images
TLDR
This work proposes a method for color imaging via compressive sampling via Compressive Sampling. Expand
Deep Dictionary Learning
TLDR
This paper focuses on combining the concepts of these two paradigms by proposing deep dictionary learning and show how deeper architectures can be built using the layers of dictionary learning. Expand
Joint reconstruction of multiecho MR images using correlated sparsity.
This works addresses the problem of reconstructing multiple T1- or T2-weighted images of the same anatomical cross section from partially sampled K-space data. Previous studies in reconstructingExpand
Hierarchical Representation Learning for Kinship Verification
TLDR
Kinship verification has a number of applications such as organizing large collections of images and recognizing resemblances among humans. Expand
