Table 1 Sensitivity, precision rate, and overlap ratio of the proposed segmentation system.
From: Optical Flow Active Contours with Primitive Shape Priors for Echocardiography
| Â | Sensitivity | Precision rate | Overlap ratio |
|---|---|---|---|
Standard GVF snake | 90.4% | 70.2% | 65.3% |
GVF snake with optical flow only | 92.8% | 76.5% | 72.2% |
GVF snake with optical flow and priors | 93.7% | 80.9% | 76.7% |
