Nonlinear optimization is a key component of many image registration algorithms. Improving registration speed is almost always desirable. One way to do this is to accelerate the optimization cost function using a parallel implementation. The purpose of this [...]

We have implemented filters for computing phase symmetry (PS) in ITK using steerable filters computed and applied in the Fourier domain. In some recent publications, phase symmetry has been shown to be a useful pre-processing measure for performing image [...]
