“Spectral data cube”. Three-dimensional structure of hyperspectral imaging data with two spatial dimensions y and x and a spectral dimension z. Each image pixel contains the spectral information over the measured range. In this example, the reflectance from barley leaves diseased with rust is illustrated at different disease severities
