3D B Spline Interval Wavelet Moments for 3D Objects

Abstract

By introducing B spline interval wavelets to the 3D wavelet moments, we give a new representation for 3D objects. The new descriptors can keep more information of the edge. They are invariant to translation, rotation and scale, and have the multi-resolution features in the radial direction, which can handle noise to some extent and provide multi-level features to satisfy various requirements. With the Pearson correlation coefficient and the energy in each level, we give a new method to measure the similarity of two objects. In the experiment, it is proved to be an efficient method.
