* One way to validate registration techniques is to assess how well primary eigenvectors align.<br />
* Reluctant to optimize the registration on the features for which you desire to statistically analyze.<br />

<br /> Comments from Tom's Talk:<br />
<br />
* Presentation of an argument for higher angular diffusion imaging (via the analysis of aligned v.s. unaligned tensors).<br />
<br />
<br /> Comments from Bruce's Talk:<br />
<br />
* Comments on ex-vivo imagery<br />
* How accessible is this nice data?<br />
** It would be nice to use this high resolution data as a ground truth for diffusion studies.<br />

<br /> Comments from Polina's Talk:<br />
<br />
* Is there any guarantee that these clusters will be compact?<br />
** There is some hope for this due to the distance measure that is used. It's not obvious.<br />
* Is this sensitive to the choice of sigma?<br />
** Look to Lauren's thesis which will be published next week. Every aspect was evaluated and shown to not be too sensitive and to be in a reasonable range.<br />
* What if you limited the tracts are constrained to have a limited length?<br />
** Then you might be able to get better results at fiber crossings.<br />

<br /> Comments from Allen's Talk:<br />
<br />
* The property of the Finsler metric ensures that the curve evolution does not prefer the tangent direction over the curve shortening.<br />
* Discussion on the minimum of curves in the Finsler geometry.<br />
* Use of particle systems in image segmentation - resolved the issue in the non-convex case.</div>Andy
