- Abstract
- In this paper we describe an application of image processing for the texture study of the use wear polishes on flint artifacts, experimentally obtained on two types of materials: wood and hide. The quantification of the textural properties of the images, obtained with a high magnification (200X) metallographic microscope strictly follows the rules indicated by HARALICK et al. in 1973. Twenty-two textural features were obtained from the image and statistical analysis then allowed the discrimination between the two classes of materials. The techniques employed, T-test and linear stepwise discriminant analysis, show that the discrimination between tools working wood and working hide is quite good, in the case of distance between the pixels = 1. Possibilities of future and more refined analyses are then discussed at the end of the paper.
