Fig. 3. Decision tree of the fine modulated model obtained in the second step, where features, decisions, and outcomes are expressed in shapes of ellipse, line, and square, respectively. Features are depicted in colored ellipses with letters enclosed, where ‘fd’, ‘pd’, ‘sd’ or ‘sz’ refer the frame-to-frame pixel difference, the frame-to-frame body position difference, the frame-to-frame body size difference or the body size, respectively. Decisions are displayed in different patterns of lines, in which solid or dotted lines are cases for the corresponding feature not to be or to be greater than the number specified beside the feature, respectively. Outcomes are displayed as a letter ‘N’ for non-scratching or ‘S’ for scratching on a colored square with white or grey, respectively.
