Discrimination of grapevine (Vitis vinifera L.) leaf shape by fractal spectrum

Discrimination of grapevine (Vitis vinifera L.) leaf shape by fractal spectrum

Vitis 41(3): 137-142

ISSN/ISBN: 0042-7500

A technique was developed (1) to digitize grapevine leaves, (2) to split the images obtained in the three components of the RGB (red, green and blue) colour system, obtain the fractal spectrum for each colour component of the leaf and (3) to calculate 15 different fractal parameters. The system, consisting of a scanning device, a personal computer and the code written in the C language, was then tested to characterize and identify 12 Sangiovese-related grapevine accessions.
