Objective
Our objective is to bring a collection of images into joint alignment.
Approach, Plan
We implemented a non-rigid groupwise registration method using sum of pixelwise entropies as a joint alignment criterion. We extended ITK's pairwise registration framework to include groupwise registration methods. The provide an efficient implementation of the objective function using a parallel implementation. We have chosen B-splines as our non-rigid deformation model and optimized ITK's B-Spline implementation.
Our plan is to incorporate our implementation into ITK and to provide test cases for validation.
Progress
The code is submitted to ITK repositories(DONE). Submission to Insight Journal.
