In this paper we propose an effective and robust approach for detecting corner points on a given binary image. Unlike other corner detection methods the proposed method is non-parametric in nature, that is, it does not require any input parameter. The proposed method is based on mathematical morphology. It makes use of morphological skeleton for detecting corner points. Convex corner points are...
This paper describes a graphical method of Skeletal Shock Graph, which is based on the shape or geometry of the object. Shock Graph is an abstraction of the skeleton of a shape onto a Directed Acyclic Graph (DAG) in which the skeleton points are labeled according to the local variation of the radius function at each point. A large image data base is created by using suitable image acquisition t...

This paper presents a robust thinning-based method for the segmentation of strokes from handwritten Chi-nese characters. A new set of feature points is proposed for the analysis of skeleton images. A geometrical graph based approach is developed for the analysis of strokes. A novel criterion is proposed for the identiication of the fork points in a skeleton image which correspond to the same jo...
Skeleton is a widely addressed topic in binary image processing and object or shape representation. The difficulty raised by the discrete nature of images has led to different classes of methods. Among the most popular ones, distance based methods led to the important notion of centers of maximal balls (CMB), and mathematical morphology based methods led both to an efficient computation of CMB ...
This paper proposed a method of human motion posture recognition using the angle characteristics of each branch. The coordinates of skeleton intersection and endpoint is extracted from the skeleton of human body image so as to calculate the branch angle parameters of head, hands and feet in human skeleton. In order to realize the matching identification of the series traffic command gestures, t...
In this paper a new algorithm is proposed for skeletonizing binary digital images. The algorithm does not employ the conventional pixelor non-pixel-based techniques. Instead, it identifies regions of particular shapes in the image and substitutes apppropriate skeleton patterns for them. Initially, as many horizontal and vertical strips as possible are detected. These correspond to rather straig...
In this paper, we propose a thinning algorithm for Arabic handwriting using color coding for both thinning processing and gap recovery in the final output skeleton. This algorithm is designed so that it accepts unconstrained Arabic handwriting. Different colors have been given to different pixels of interest on the original image in the beginning and during the process of skeletonization. Color...
