Components of Hammer Attribute Vectors.
Similarity map (middle column) computed on moving image (right) for the selected point on the fixed image (left, cross). Point indicated by a cross on the middle and right column is the point on the moving image that is the most similar to the picked point on the fixed image.
The output deformation filed by HAMMER.

Objective
We will continue developping and testing HAMMER registration algorithm implemented using ITK. The goal is to have an initial version ready by the end of the week that can be distributed within NA-MIC community for more extensive testing.
Approach, Plan
We will develop a Slicer module for the current implementation of the Hammer registration algorithm and test on images from multiple sources to make the algorithm robust and easy to use. Base line results and test will be generated.
Progress
Since summer project week in Boston, we have integrated HAMMER into Slicer as a moduler. Each component has been tested. We have made the tutorial to present how to use HAMMER in Slicer3. The source code is version controlled at NITRC site. The current development corresponds to the original Hammer algorithm that is based on tissue classification of T1 weighted images (as outlined on the first HAMMER paper).
Users List
We have released our registration method to the Na-mic society. Below is the list of users:
1. Minjie Wu, Geriatric Psychiatry Neuroimaging Lab, University of Pittsburgh
