3D search and retrieval using Krawtchouk moments

In this paper a combination of a rotation invariant method with a method which utilizes rotation normalization is proposed. Both methods used are based on 2D/3D Krawtchouk moments. The first method is an extension of that which was originally introduced in [ 1] and utilizes 2D Krawtchouk moments while the second method was originally introduced in [ 2] and utilizes 3D Krawtchouk moments.
