Abstract
For decades, it has been known that the morphology of wild Vitis vinifera (grape) pips differ from domesticated ones. Based on these differences, computerised image analysis and morphometrics allow us to obtain excellent results to identify the domestication status of archaeological grape pips. However, various image analysis methodologies and morphometric methods have been applied in previous studies for this purpose. Our study has examined, for the first time, the different techniques of digital image acquisition (digital camera vs. scanner) of grape pips, with the aim of testing the identification performance using both traditional and geometric morphometric features to distinguish wild from domestic grape pips. The performance of different morphometric methods established that all image acquisition techniques and morphometric methods correctly distinguished between wild and domestic grapes. The use of the combined geometric morphometric features of both dorsal and lateral views of the pips provided the best accuracy in distinguishing individual cultivars.
