Multispectral and Hyperspectral Image Fusion Using a 3-D-Convolutional Neural Network

no code implementations16 Jun 2017 Frosti Palsson, Johannes R. Sveinsson, Magnus O. Ulfarsson

In this paper, we propose a method using a three dimensional convolutional neural network (3-D-CNN) to fuse together multispectral (MS) and hyperspectral (HS) images to obtain a high resolution hyperspectral image.

Hyperspectral Subspace Identification Using SURE

no code implementations1 Jun 2016 Behnood Rasti, Magnus O. Ulfarsson, Johannes R. Sveinsson

However, due to spectral and spatial redundancy the true hyperspectral signal lies on a subspace of much lower dimension than the original data.

Classification of Big Data with Application to Imaging Genetics

no code implementations16 May 2016 Magnus O. Ulfarsson, Frosti Palsson, Jakob Sigurdsson, Johannes R. Sveinsson

In this paper, we consider the problem of classifying p>>n data and propose a classification method based on linear discriminant analysis (LDA).

MIST: L0 Sparse Linear Regression with Momentum

no code implementations25 Sep 2014 Goran Marjanovic, Magnus O. Ulfarsson, Alfred O. Hero III

Significant attention has been given to minimizing a penalized least squares criterion for estimating sparse solutions to large linear systems of equations.
