【Abstract】 A new parallel thinning method based on image marking is proposed in this paper.First,the distance from every pixel to its nearest contour is calculated.Then these distances will be constructed as a marking image of the original one and inputted for thinning.The experimental results have demonstrated that the proposed approach can achieve comparable satisfactory performance in terms of keeping geometrical properties and robustness to single pixel noise by the integrative usage of the marking information.Moreover,the method presented will also benefit the basis for further graph recognition.更多还原
