Hi, I have a Hyperion EO-1 … WebbA common task in hyperspectral image processing is to classify a data cube. For example one might want to match pixels to reference endmembers. The Spectral Angle Mapper (SAM) algorithm [1] does that by computing a spectral measure between each pixel and the references. The spectral angle of a pixel x with a reference pixel r is defined by ...

WebbDue to the imaging mechanism of hyperspectral images, the spatial resolution of the resulting images is low. An effective method to solve this problem is to fuse the low-resolution hyperspectral image (LR-HSI) with the high-resolution multispectral image (HR-MSI) to generate the high-resolution hyperspectral image (HR-HSI). chase gopher repellentWebb1 aug. 2012 · DOI: 10.1016/J.CHEMOLAB.2012.05.009 Corpus ID: 122368728; Pre-processing of hyperspectral images.
