EarthMapper: A Tool Box for the Semantic Segmentation of Remote Sensing Imagery

1 code implementation1 Apr 2018 Ronald Kemker, Utsav B. Gewali, Christopher Kanan

Deep learning continues to push state-of-the-art performance for the semantic segmentation of color (i. e., RGB) imagery; however, the lack of annotated data for many remote sensing sensors (i. e. hyperspectral imagery (HSI)) prevents researchers from taking advantage of this recent success.

A Tutorial on Modeling and Inference in Undirected Graphical Models for Hyperspectral Image Analysis

2 code implementations25 Jan 2018 Utsav B. Gewali, Sildomar T. Monteiro

However, graphical models have not been easily accessible to the larger remote sensing community as they are not discussed in standard remote sensing textbooks and not included in the popular remote sensing software and toolboxes.

Multitask Learning of Vegetation Biochemistry from Hyperspectral Data

no code implementations22 Oct 2016 Utsav B. Gewali, Sildomar T. Monteiro

Statistical models have been successful in accurately estimating the biochemical contents of vegetation from the reflectance spectra.

Spectral Angle Based Unary Energy Functions for Spatial-Spectral Hyperspectral Classification using Markov Random Fields

no code implementations22 Oct 2016 Utsav B. Gewali, Sildomar T. Monteiro

We compare the proposed methods with the state-of-the-art Markov random field methods that use support vector machines and Gaussian processes with squared exponential kernel/covariance function.
