## Tensor Robust Principal Component Analysis: Exact Recovery of Corrupted Low-Rank Tensors via Convex Optimization

This paper studies the Tensor Robust Principal Component (TRPCA) problem which extends the known Robust PCA to the tensor case.

## An Anisotropic Diffusion PDE for Noise Reduction and Thin Edge Preservation

An image denoising operator defined by a non-linear partial differential equation(PDE) is presented, which can remove noise, enhance step-like edges and keep the locality of the edges.
