Surface texture characterization of an Italian pasta by means of univariate and multivariate feature extraction from their texture images

► Surface texture is an important characteristic of pasta. ► It can be evaluated by means of image texture analysis methods. ► Thanks to GLCM the surface characteristic of the samples was estimated objectively. ► Results showed the differences of surface aspect of pasta before and after cooking. ► PCA/PLS-DA analysis was applied on GLCM/AMT results; sample classification was found.
