Linear Data Compression of Hyperspectral Images
AbstractThe aim of the paper is to analyse hyperspectral images using tensor principal component analysis of multi-way data sets. Because of high-resolution sampling in the colour channels, images observed by a hyperspectral camera system are expressed by three-mode tensors. The Tucker-3 decomposition of a three-mode tensor is used in behaviourmetry and psychology for the extraction of relations among three entries as an extension of the usual principal component analysis for statistical analysis. Hyperspectral images express spectral information of two-dimensional images on the imaging plane. Therefore, for statistical analysis, we adopt the Tucker-3 decomposition. The Tucker-3 decomposition of hyperspectral images extracts statistically dominant information from hyperspectral images. Tensor principal component analysis allows us to extract dominant light-channel information from hyperspectral images.
