Meeting Dec 12 05

From Utah Center for Neuroimage Analysis

Summary:

• We looked at the 3 consecutive slices from the microneuroma data set that we have put together with our automatic mosaicking tool. Before we can start tracking, we will need to correct for rotation and global warping (2nd or 3rd degree polynomial). We plan to achieve this with a landmark based approach. For these low degree transformations, we will consider only very prominent landmarks such as holes (big white blobs) and pigment granules (somewhat smaller black blobs). These landmarks will likely appear to some extent in all slices.

• Liz summarized her progress with ellipse fitting and showed results on the artificial image she has created.

• Melissa has tracked 2 axons through ~900 slices using Zebraviewer and plotted the resulting path using gnuplot. The 2 axons start adjacent to each other and stay that way until the last ~100 slices, where they start separating.

• Robert is going to look into possible venues for publishing the mosaicking work.
