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.

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.

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.
