Summary:
The human age for medico-legal purposes is usually estimated from hard tissues like bones and
teeth. Only little attention was paid to soft tissues most probably due to the lack of detectable age
changes. This study deals with colour changes of human tissue from intervertebral discs, Achilles
tendon and rib cartilage in the relation to the age. The image analysis of colour of investigated
tissue samples was performed. The values of intensities of channels RGB (MeanRed, MeanGreen,
and MeanBlue) and parameters from the IHS system (MeanSaturation, HueTypical, HueVariation,
BrightVariation and MeanBrightness) were evaluated. The results confirm that colour changes of
some tissues can be used for age estimation.
Key words:
age estimation – colour changes of tissues – non-enzymatic browning – image analysis
