| Popis: | We propose a new vessel profile characterization and comparison technique, based on Modal Analysis. Each profile is represented as a node chain that approximates its contour, and characterized by calculating its deformation spectrum, i.e. the amount of deformation needed to transform it into a reference shape. Two profiles can be compared by computing the Euclidean Distance between their corresponding deformation spectrum vectors. We have done our supervised classification experiments with a profile database labeled by experts. Success rates, which exceed 89 %, are better than the ones obtained by other techniques, while maintaining a low computational cost. Our results suggest that the proposed descriptor captures the morphological features of a given profile. |
