Non-negative Tensor Patch Dictionary Approaches for Image Compression and Deblurring Applications

no code implementations25 Sep 2019 Elizabeth Newman, Misha E. Kilmer

Building on that work, in this paper, we use of non-negative tensor patch-based dictionaries trained on other data, such as facial image data, for the purposes of either compression or image deblurring.

A Tensor-Based Dictionary Learning Approach to Tomographic Image Reconstruction

no code implementations8 Jun 2015 Sara Soltani, Misha E. Kilmer, Per Christian Hansen

Our approach differs from past approaches in that a) we use a third-order tensor representation for our images and b) we recast the reconstruction problem using the tensor formulation.

Tensor-based formulation and nuclear norm regularization for multi-energy computed tomography

no code implementations19 Jul 2013 Oguz Semerci, Ning Hao, Misha E. Kilmer, Eric L. Miller

Specifically, we model the multi-spectral unknown as a 3-way tensor where the first two dimensions are space and the third dimension is energy.
