Hyperspectral dataset: Ceramic tiles in dry and underwater setting

<p>The objective of this experiment was to observe the changes in spectral information of a calibration tile when placed underwater. For this purpose, the SPECIM IQ hyperspectral camera was used which operates in Visible and near infra-red regions (400-1000nm) with a spectral resolution FWHM of 7nm resulting in 204 bands in a data cube.</p> <p>To establish a baseline for comparison, data was acquired before submerging the calibration tile into water. Then the tile was immersed in water and data was recorded under two settings i.e., outdoor and indoor. The latter provided a controlled environment where a halogen lamp was used as the light source. Lastly, the tile was removed and data was captured both outside and inside once it had dried off. The data was annotated&nbsp;to enable comparison of similar data points under different conditions.</p> <p>&nbsp;</p>
