A Combined Random Forests and Active Contour Model Approach for Fully Automatic Segmentation of the Left Atrium in Volumetric MRI

Figure 6

Multiple slices of the 3D segmentation results for case B006 of the STACOM database. The final contours (shown as colored contours in the 1–7 columns) and the 3D surface models (shown as blue volumes in the last column) overlaid on the corresponding axial slices (a), the sagittal slices (b), and the coronal slices (c), respectively. The red contours are generated by the proposed algorithm, while the blue contours represent the ground truth, and the green contours are where the algorithm ones coincide with the ground truth.
