A new approach to fast calculation of moments of 3-D gray level images

Fast computation of three-dimensional (3-D) moments is an important and pra gmatic problem. In this paper, we propose a new algorithm together with sui table systolic structure for the fast computation of 3-D moments, extending our method for fast computation of 2-D moments. A scalable systolic struct ure, consisting of adders and latches, fully exploits parallelism of the ne twork architecture and is very suitable for hardware implementation. Our ne w method, which also dispenses with the need for multiplication, is suitabl e for both binary images and gray level images. We also extend our method t o efficient computation of k-dimensional (k-D) moments (k > 3). (C) 2000 El sevier Science B.V. All rights reserved.
