| DS001 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.
