The modelling of a perception is controlled by the user‘s expectation as additional input. Thanks to this additional information, the modelling process can be much more targeted compared to other methods.


The user constrains expectations in form of colors to selected spectra from the scene. The modelling process calculates a model which tends to follow the user‘s expectation. By applying this model to the whole scene, a perception of the whole scene is obtained.
If the user‘s expectations can be modelled, the reached perception will be near to the user‘s expectation.

User Interface

After assignment of colors to previously selected spectra, a model is calculated and applied to a selected HS cube shown to the right in the Model perspective. Uncheck spectra sets which should not be used for modelling.
Set the selectivity parameter to get either a robust or a sensitive model.

Work Flow

  • Select a spectra set per object of interest in the scene.
  • Constrain your expectation by assigning colours to the spectra sets.
  • Inspect gained perception (match with your expectations).
  • Apply pre-processing and in parallel compare results with your expectations.
  • Control the selectivity of the modelling process. Hint: try to get a “robust” setting rather than a “sensitive” one.
  • Save the model for later usage (e.g. to set up the live streaming).
