The lddmm software has been expanded to support volume, surface and points through the modules in the Large Deformation Diffeomorphic Metric Mapping (LDDMM) Suite

• lddmm-volume
• lddmm-surface
• lddmm-similitude
• lddmm-landmark
• lddmm-dti

Changed Large Deformation Metric Mapping to Large Deformation Diffeomorphic Metric Mapping (LDDMM) on the web pages.

More MayaVi visualizations:

• Used the Threshold filter to clean up the Velocity Vector field: Volume with Velocity Threshold
• Same model, but a close-up from a different angle: Volume with Velocity Threshold Closeup
• Here is a composition of the deformed patient at timestep 0 (shown in red) rendered with the image at timestep 9 (green): Angle 1 ; Angle 2

We now have fully gathered vtk files for some datasets. Experimented with different visualizations. Examples can be seen here:

• Volume with Velocity Vector Cut Plane
• Volume with Velocity Vectors 1
• Volume with Velocity Vectors 2

Attended Faisal's thesis defense. Good work!

Created an example movie (MPEG - 455 KB) from Patientdef* files. Still images were created with this Python script

Here is a second movie (MPEG - 630 KB). This movie was created using one timestep from the Patientdef files, and includes a moving vector cut plane. In addition, vectors below a certain threshold were removed, and the remaining vectors were lengthened by a factor of 2 for increased visibility.

Converted the ldmmtovtk program java to c++. This allow or the program to become a library routine for ldmm.

Last week I worked on getting multi-channel data into vtk. I have fixed some errors in the blox to vtk file version and I can now take multi-channel data back and forth between LDDMM VTK and BLOX. I am currently working on reading the multicomponents in VTK and I have not yet found how to get the 2 and 3 channels to display. I will work on that and on getting display of faisl's data this week.

This week I have finished working on 1 component VTI VTK files. I have tested and verified this week the LDDMM file to Blox conversion and I have tested 1 channel VTI VTK files as well.
