Thanks to Rob Webb from Stemmer Imaging Ltd. who provided an example data set to an apple with bruises on it!


Example Data: Apple with bruises

Description: The example project apple with bruises shows an apple with bruises on it measured by NIR (near infrared) HS (hyperspectral) line-scan technology.

Usage: This data can serve to show contact-less bruises detection by HS camera technology.

Donor: Rob Webb, Stemmer Imaging Ltd, United Kingdom

Measurement System: Stemmer Imaging CCI Setup

Further notes: I carried out this example data with a conventional lighting setup - direct lighting from two sides. Therefore, the measurement data appears not to be the very best quality - especially on the borders the insufficient lighting situation results in spectra with less quality compared to those from the centre of the apple. However, by means of the CCI method Correlate I was able to extract a colour image showing all bruises available in reddish colour.

Accessible by everyone from Perception Wiki >> Download >> Example Data.


Get a demo version of Perception Studio and carry out your perceptions like Rob did.

In the next weeks (till begin of September) the Wiki service might be down from time to time due to maintenance work of the server.
Especially on August 16th, we await an interruption for several hours. Please let us know if printable copies of partially content would help in the meantime.

Sorry for the inconvenience

Chemical Colour Imaging -
the next step in the evolution of machine vision

(white paper)

CCI - the next step in the evolution of machine vision.pdf






Chemical Colour Imaging (CCI) makes complex hyperspectral data on a molecular level usable for machine vision. Hyperspectral imaging systems based on a generic, intuitive configurable data processing platform make the scientific methods of hyperspectral analysis accessible for everyone and open up new application areas.

This white paper describes Chemical Colour Imaging (CCI) as the next step in the evolution of machine vision, summarizes the current state of technology as well the relevance of CCI for the machine vision community.


...also available together with other informaton to technology on the training space.


  • Improvement on the installation process: library folder structure is now much more reduced.
  • Bug fix on license activation: Now existent license activations dont get overwritten (by new ones) anymore.
  • Bug fix: Trigger parameters of GEV cameras are now optionally accessible from the setup perspective.

Available installers:
