Figure 2

Graphical representation of one level set model. The green line denotes the contour curve, which divides the image into two regions, interior region C 1 and the exterior region C 2 (a). The local neighborhood of x, K σ (y - x) is represented by the black circle. The circle is spilt by the green curve into local interior (red) and local exterior (green) regions. The small yellow and blue dots represent the point x along the contour and point y in the local region of point x, respectively. f 1(x) and f 2(x) are computed in the local interior and local exterior region of the point x to fit the image intensities near the point x (b). f 1 (y) and f 2 (y) are computed in the local interior and local exterior region of the point x to fit the image intensities near the point y (c).
