The example project apple with bruises shows an apple with bruises on it measured by NIR (near infrared) HS (hyperspectral) line-scan technology.
|Title||Apple with bruises|
|Sample Description||An apple with a large bruise on it. See sample image below. The reddish region in the centre shows the bruise. Some other bruises are located near the stem.

|Measurement Description||Measurement in reflection|
|Measurement Setup||Lighting: Halogen (2x400W spots, 2-sided), Background: white coated transport tray (made of wood), tInt=12ms, Gain=low|
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.
