An Assessment Method for Ink Marks

A similarity test based on the context of the skeleton is put forward to evaluate the similarity between two brush inks. The context information of skeleton points is computed after the skeleton points of strokes from virtual ink and true ink are collected to obtain the similarity of different ink. The similarity of strokes from two inks is embodied by the sum of similarity of all skeleton points. It is proved that the similarity can be 0-1 and the larger value representing more similar of the two inks. The number of skeleton points makes no difference to the conclusion. Both experiments demonstrated that it is feasible of the method based on the context of skeleton points.
