Learning Sparse Representations of Depth [PDF]

open access: yesIEEE Journal of Selected Topics in Signal Processing, 2011
This paper introduces a new method for learning and inferring sparse representations of depth (disparity) maps. The proposed algorithm relaxes the usual assumption of the stationary noise model in sparse coding. This enables learning from data corrupted with spatially varying noise or uncertainty, typically obtained by laser range scanners or ...

Sparse Representation Based Projections [PDF]

open access: yesProcedings of the British Machine Vision Conference 2011, 2011
In dimensionality reduction most methods aim at preserving one or a few properties of the original space in the resulting embedding. As our results show, preserving the sparse representation of the signals from the original space in the (lower) dimensional projected space is beneficial for several benchmarks (faces, traffic signs, and handwritten ...

Voxel selection in fMRI data analysis based on sparse representation [PDF]

open access: yes, 2009
Multivariate pattern analysis approaches toward detection of brain regions from fMRI data have been gaining attention recently. In this study, we introduce an iterative sparse-representation-based algorithm for detection of voxels in functional MRI (fMRI)

Local Connectivity Enhanced Sparse Representation

open access: yesIEEE Access, 2020
During the past two decades, the subspace clustering problem has attracted much attention. Since the data set in real-world problems usually contains a lot of categories, it seems that the large subspace number (LSN) subspace clustering has great ...
