Prince, Department of Electrical and Computer Engineering, Johns Hopkins University. | | Surfaces displays a sequence of contours as a time-motion display. Contour sequences can be averaged and compared numerically. |
Future Developments A more comprehensive version of Surfaces is being developed: the Contour Analysis and VIsualization TEchniqe (CAVITE) . CAVITE will add three pre-processing modules: - Time alignment of multiple repetitions.
- Spatial alignment of multible repetitions.
- Rigid body alignment of palates for alignment of tongue data sets.
