Fig. 2.

The basic flowchart of regression-based deformable model. Yellow contours in the leftmost and rightmost figures indicate the initialized deformable model and the final segmentation, respectively. In the middle two figures, color indicates the magnitude of estimated displacement. Blue and red indicates small and large magnitudes, respectively. The magnitude increases with the following color ordering: blue, cyan, green, yellow and red. The colder the color is, the smaller the magnitude is.
