Weekly progress report
To Do:
- Automating landmark selection
- Documentation
| Week | Tasks |
| Aug 25 - Aug 29 | Aug 25-29 (China) |
| Aug 18 - Aug 20 | Automating landmark selection
... research on landmarks and morphometrics
... 3D SIFT feature detection
Setting up SVN repository
Fixing landmark selection GUI
Aug 21-22 (China) |
| Aug 12 - Aug 15 | Documenting work flow
Automating landmark selection
... research on landmarks and morphometrics
Aug 11 (New York) |
| Aug 5 - Aug 7 | Complete Ian/OW/Peter comparison
Documenting work flow
Research on methods for automating landmark selection
Aug 4 (BC Day)
Aug 8 (New York) |
| Jul 28 - Aug 1 | Create mesh from segmented Ian tongue
... generate smooth surface in Amira
... Perl script to convert to OBJ file
Morph Ian tongue mesh into Ian MRI and OW MRI
... use GUI with segmented Ian tongue mesh as reference model
... calculate error with LW segmentations
Compare OW volunteer MRI with actual OSA patient MRI
... performed LW segmentation to see differences |
| Jul 21 - Jul 25 | Overweight volunteer vs. Ian
... performed LW segmentation of tongues
... compared in Amira
Merged MRI sets (w/ Bruno)
... registered and merged data sets using different settings
... performed LW segmentation of tongues
... compared in Amira
Wrap up unimodal segmentation
... summarized work on sagittal-dataset-only segmentation |
| Jul 14 - Jul 18 | Error between warp result and LW output
... error method #1: sum of shortest distance from each warp point to a LW point
... error method #2: sum of shortest perpendicular distance from each warp face to a LW point
... executed more warp trials using different sets of corresponding landmark points
... got error for each landmark set to find set with minimal error
Landmark selection GUI
... modified and stripped down warp GUI for Hui's usage in selecting/exporting landmark points
Wrap up unimodal segmentation
... summarized work on sagittal-dataset-only segmentation |
| Jul 7 - Jul 11 | Jul 7 - Jul 11 (Hawaii) |
| Jul 1 - Jul 4 | Error between warp result and LW output
... 3D Livewire revisit: resegmented tongue
... visually compare results in Amira
... translation transform on LW output to align with warp result
... calculated error: for all intermediate warp result points, sum distances to closest LW surface points
Artisynth export
... tweaked settings (eg. g-force, muscle excitations) in Artisynth so tongue shape is similar to MRI position
... exported new nodes and muscle excitations
