Multidimensional Elastic Registration of Images Using Splines

J. Kybic, M. Unser

Proceedings of the 2000 Seventh IEEE International Conference on Image Processing (ICIP'00), Vancouver BC, Canada, September 10-13, 2000, vol. II, pp. 455–458.

We present an algorithm for nonlinear multidimensional registration. The correspondence function is represented in a spline space, as well as the volumes being registered. We also use the cubic splines to interpolate the volumetric data to be registered. We use a multiresolution strategy, which gives us robustness and additional speedup. We analyze the computational complexity of the algorithm and its performance using different multidimensional optimization methods. Finally, we present an application of the algorithm for registering ECD SPECT images for realignment of corresponding Xenon inhalation SPECT images.
