Three dimensional surface matching is an important problem in computer vision. The process of surface matching is to match similar regions or correspondences across multiple surfaces with unknown relative poses. Many surface descriptors for finding correspondences have been proposed. However, most of these approaches have been used in triangle mesh surfaces. In this paper, a local surface descr...

This paper introduces a new set of orthogonal moment functions based on the discrete Tchebichef polynomials. The Tchebichef moments can be effectively used as pattern features in the analysis of two-dimensional images. The implementation of moments proposed in this paper does not involve any numerical approximation, since the basis set is orthogonal in the discrete domain of the image coordinat...

Most methodologies not only differ in the kind of techniques used to pinpoint the location of landmarks but in many other ways like: the size of training and test dataset, quality and variations covered in the dataset based on age, race, gender, etc., different studies use distinctive landmarks and different methodologies to report the results. In this Chapter, we propose a combination of local...
