This data can serve to show contact-less bruises detection by means of a NIR (near infrared) hyperspectral imaging camera.

Further notes of the data sets donor

I carried out this example data with a conventional lighting setup - direct lighting from two sides. Therefore, the measurement data appears not to be the very best quality - especially on the borders the insufficient lighting situation results in spectra with less quality compared to those from the centre of the apple. However, by means of the CCI method Correlate I was able to extract a colour image showing all bruises available in reddish colour.
