Visualization of Circular versus Elliptical Methods

Figures 9.45-9.48 show the comparision between the outputs of the systems when the system uses circular ROI versus elliptical ROIs. The visualization results from the two systems (one with circular ROI vs. elliptical ROI) are shown in pairs: top row corresponds to circular ROI methodology, while bottom row corresponds to elliptical ROI. Note that the equation for computing the elliptical ROI is shown in Eq. (9.25).

Figure 9.46: 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.
