Coffee beans mixed with stones
near infrared 319x359 156 coffee_mix1022.zip
[69 MB]
This remarkable dataset contains the hyperspectral image of a mixture of coffee beans and rocks. The spectra exhibit lots of spikes and saturated regions which form an excellent test case for algorithms detecting and correcting artifacts in hyperspectral images.
