Although hyperspectral images contain much more information than regular RGB images, more than ninety percent of the variance can be explained by a small portion of the data. The goal of dimension reduction is to map high dimensional data into a lower dimension while preserving the main features of the original data. The dimension reduction codes are taken(More)
Hyperactive is a Matlab graphical user interface (GUI) that can display multidimensional data and analyze it by running different combinations of clustering methods and distance measures. Most of the functions (labeled with ST below) in this program require the Matlab Statistics Toolbox. The hyperspectral images Urban and Terrain we have been working with(More)
Dosimetric consequences of plans optimized using the analytical anisotropic algorithm (AAA) implemented in the Varian Eclipse treatment planning system for spine stereotactic body radiotherapy were evaluated by re-calculating with BEAMnrc/DOSXYZnrc Monte Carlo. Six patients with spinal vertebral metastases were planned using volumetric modulated arc(More)
