This data set gives an example on industrial impurity detection. So the discrimination of objects (impurities) from product (sausage) can be investigated.

Further notes of the data sets donor

Beside the sausage_plastics (979-1652nm) an additional hyperspectral cube is available named sauasage_plastics_highSpeed. The "highSpeed" data set was obtained by measuring the same object but in a reduced spectral range: 1071-1268nm (resolved by 121 spectral points).
The "highSpeed" data set shows the possibility to speed up the camera system (scan rate) by decreasing the number of spectral points to be read from the sensor.
High speed measurement is mandatory for this kind of industrial application (impurity detection) since the transport speed of objects is typically high (1-2m/s) and size of impurities typically small (in the millimeter range and smaller).
