Object Recognition Using the Shape Filling Rate

The shape context algorithm is sensitive to the variance of the articulation relative position.A shape recognition method is proposed in this paper by using the information of the local shape filling rate of object silhouettes.The ratio of the shape silhouette pixels over the total pixels is defined as the local shape filling rate and it takes the landmark point as the center of circle having different radius.The shape filling rates of all the landmark points with different radius constitute a characteristic matrix that reflects the object entire statistical property.The new approach is tested on a variety of shape databases.The novel method has strong power to describe the object details.It is insensitive to articulation and the quantity of landmark points.
