A scene is described as a mix of pure components (constituents). The resulting perception is based on correlation information of pure components to the scene.



A spectra can be a mix of different spectra of pure components. By knowledge of  „all“ pure components, a correlation value per component and pixel can be calculated. By assignment of component score images to colour channels, a perception is gained.

User Interface

The correlation of selected spectra is calculated to selected HS cube. The value per component (spectra) is shown through a score image (correlation image) at the bottom right of the Model perspective.
By assignment to color channels, a CCI image is obtained (shown to the right of the data view).

Work Flow

  • Select a spectra set per pure component available in the scene. Hint: give the spectra a meaningful name.
  • Inspect gained component score images (match with your expectations).
  • E.g. apply pre-processing and in parallel compare results with your expectations
  • E.g. crop the scene to focus only on objects of interest.
  • E.g. set the scaling to selected spectra to arrange the colour contrast in the result
  • Assign those components to colour channels which best describe application relevant information.
  • Save the model for later usage (e.g. to setup the live streaming)


Be sure to select pure components.
