查询词典 combinatorial closure

In the key step of this method (the process of contour tracking), the paper puts forward the concept of grid right-correlation flag to determine the initial segment of tracking curve. In the tracking procedure, the trend of subsequent points are determined by the combinatorial values of neighborhood cells, and a method is designed to avoid contours crossing. In order to obtain high-quality contour line, it adopts it adopts the linear interpolative method to show a contour chart of accurate localization and better visual effect.
