CVB Spectral allows users to acquire the spatial and wavelength information direct from a hyperspectral camera or from files in the form of ENVI datacubes (x, y and wavelength). At the most basic level, the tool can slice the datacube to create 2D image data. This can be spatial (x,y) at a specified wavelength, or spatio-wavelength data. Transposing and cropping datacubes can be done remarkably quickly as no copying of data is required. This then allows further processing by conventional image processing tools.
For cubes in the visible spectrum, CVB Spectral allow conversion to XYZ, sRGB and Lab colour image formats. The tool also allows a selection of standard observers to account for a standardised response to colour. There is also a choice of standard illuminants to account for different light sources.
The metadata present in datacubes often provides format and wavelengths of the data, so this is easily available within CVB Spectral.
