System Weakness

The ROI is determined by looking at the overlay of the ground truth contour and the grayscale image. The center is estimated by eye and the radius of the contour

Figure 9.48: Results of estimated boundary using circular- vs. elliptical-based methods. The system used was FCM based. Top rows are circular-based ROI, while the corresponding bottom rows are elliptical-based ROIs.

in most cases is the farthest distance from the center to a point on the contour. The ROI is the circle given by this center and this radius. The center and radius are sometimes adjusted after seeing the result of the pipeline's first run.
