## Globally Variance-Constrained Sparse Representation for Rate-Distortion Optimized Image Representation

A Globally Variance-Constrained Sparse Representation (GVCSR) model is proposed, where a variance-constrained rate term is introduced to the conventional sparse representation.

## Tensor LRR and Sparse Coding Based Subspace Clustering

We propose a tensor low-rank representation (TLRR) and sparse coding-based (TLRRSC) subspace clustering method by simultaneously considering feature information and spatial structures.
