The lddmm software has been expanded to support volume, surface and points through the modules in the Large Deformation Diffeomorphic Metric Mapping (LDDMM) Suite2005.09.19
Updated the BIRN Portal section adding ParaView example with Mouse BIRN data.2004.07.21
Updated the BIRN Portal section.
Changed Large Deformation Metric Mapping to Large Deformation Diffeomorphic Metric Mapping (LDDMM) on the web pages.2003.07.22
More MayaVi visualizations:2003.07.21
- 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:2003.07.17
Attended Faisal's thesis defense. Good work!
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.2003.04.24
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.
