Semiautomatic Epicardial Fat Segmentation Based on Fuzzy c-Means Clustering and Geometric Ellipse Fitting

Figure 4

The resulting fuzzy cluster that is considered to contain epicardial fat tissue, for the image slice example shown in Figure 3. White color-marked regions show clustered data (a), yellow color-marked pixels indicate ellipsoidal shape fitting approach (b), and red color-marked lines denote the angular bandwidth constrain (c).
