Motivated from spectroscopic work in laboratories, an approach to unscramble spectra into their principle components is employed.
An unscrambling process is controlled by the maximum variance information in selected spectra. The perception gained is composed of score values of calculated principle „patterns“ in the spectra. By assigning components to colour channels (which hold application relevant information), a perception is obtained based on principle components.
Principle components are extracted unsupervised from selected spectra.
The value per component is shown through a score image at the bottom right of the Model perspective.
By comparison of the score images to expectations and assignment to color channels, a CCI image is obtained (shown to the right of the data view)
- Select spectra from the scene which potentially holds information of interest.
- 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).
Often this is done by switching through the preprocessing methods and comparing the results with expectations.
the extraction process doesn't necessitate knowledge about observed objects.
the component extraction is done in a statistically well validated way.

might fail when components of interest are interfered by much stronger side-components such as noise.
