چکیده

Hyperspectral image and videos provide rich spectral information content, which facilitates accurate classification, unmixing, temporal change detection, so on. However, with the rapid improvements in technology, data size has increased many folds. To properly handle enormous volume, efficient methods are required to compress data. This paper proposes a multi-way approach for compression of hyperspectral or video sequence. In this approach, differential representation is first obtained. case images, difference between consecutive bands obtained videos, frames computed. next step, sparse Tucker tensor decomposition performed core Finally, corresponding factor matrices truncated encoded obtain compressed version transmission. The method utilises structure hence can be extended videos. Experimental results on several real imply that proposed obtains better efficiency terms ratio, signal noise ratio.

BTF Compression via Sparse Tensor Decomposition

In this paper, we present a novel compression technique for Bidirectional Texture Functions based on a sparse tensor decomposition. We apply the K-SVD algorithm along two different modes of a tensor to decompose it into a small dictionary and two sparse tensors. This representation is very compact, allowing for considerably better compression ratios at the same RMS error than possible with curr...

Multifactor sparse feature extraction using Convolutive Nonnegative Tucker Decomposition

Multilinear algebra of the higher-order tensor has been proposed as a potential mathematical framework for machine learning to investigate the relationships among multiple factors underlying the observations. One popular model Nonnegative Tucker Decomposition (NTD) allows us to explore the interactions of different factors with nonnegative constraints. In order to reduce degeneracy problem of t...

Bayesian Sparse Tucker Models for Dimension Reduction and Tensor Completion

Tucker decomposition is the cornerstone of modern machine learning on tensorial data analysis, which have attracted considerable attention for multiway feature extraction, compressive sensing, and tensor completion. The most challenging problem is related to determination of model complexity (i.e., multilinear rank), especially when noise and missing data are present. In addition, existing meth...

Alternating proximal gradient method for sparse nonnegative Tucker decomposition

Multi-way data arises inmany applications such as electroencephalography classification, face recognition, text mining and hyperspectral data analysis. Tensor decomposition has been commonly used to find the hidden factors and elicit the intrinsic structures of the multi-way data. This paper considers sparse nonnegative Tucker decomposition (NTD), which is to decompose a given tensor into the p...
