******************************************************************************* Potato Hyperspectral Images Database Laboratory of Applied Computer Science (LIA2) Universidade de Vigo, Spain http://lia.ei.uvigo.es ******************************************************************************* INTRODUCTION The purpose of this database (md5-checksum on server) to provide to the research community a set of hyperspectral images which we used to detecting the hollow heart in potatoes using hyperspectral information in the infrared spectra (900nm to 1700nm). This database has been used in some articles and in a PhD dissertation: http://www.angeldacal.com/files/publications/angeldacal_2011_CAIP.pdf (English) http://www.angeldacal.com/files/tesis_angeldacal.pdf (Spanish) The images have been acquired using a hyperspectral system composed by: - Camera Xenics Xeva-1.7-320 (sensor InGaAs, 900nm - 1700nm, 320x256, USB 2.0) - Specim Imspector N17E (900nm - 1700nm, spectral resolution 5nm) - Mirror Scanner Specim - Halogen lamps - Optic table and other optic components ******************************************************************************* INFORMATION - The database is composed by 468 hyperspectral cubes (numbered from 1 to 468). - Each hyperspectral cube is composed by 256 monochrome images (320x320 pixels) in .bmp format. - Each image in a hyperspectral cube is identified to a wavelength, from 0839.95 nm to 1673.91 nm. - Each folder (hyperspectral cube) is followed by a 'CH' or a 'N'. A 'N' means that the potato is healthy (there are 260 healthy potatoes). A 'CH' means that the potato has a hollow heart (there are 208 hollow heart affected potatoes). ******************************************************************************* REFERENCE Please, reference this database using the following publication: A.
