Cocoa beans spectral image with three fermentation levels

The target scene consists of a black cardwith six cocoa beans of three different fermentation levels (High, correct, and low fermentation),two beans for each class, whosefalse-color composite is shown in the provided Figure (a),ground-truth map is shownin Fig. (b), and Fig. (c) presents its representative spectralsignatures. The spectral imagewas acquired by the AVT Stingray F-080Bcamera by acquiring one band each time from350 - 950 nm. The acquired image hasa spatial resolution of 1096x712 pixels and 300 spectral bands of 2 nm width.
