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.


Function

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 assigning component score images to color channels, a perception is gained.

User Interface

The correlation of selected spectra is calculated for the 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).
  • Apply preprocessing and in parallel compare results with your expectations.
  • Crop the scene to focus only on objects of interest.
  • Set the scaling to selected spectra to arrange the color contrast in the result.
  • Assign those components to color channels which best describe application relevant information.
  • Save the model for later usage (e.g. to set up the live streaming).

Hints

Make sure to select pure components.
