摘要

形状上的“重要”或突出点的定义是计算机图形学中一个古老而基本的问题。重要的点，我们称之为关键点，可以用来表示一个形状(例如，作为折线的顶点或样条的结)。与感知上的突出点相对应的关键点可以作为编辑的手柄。在简化形状时，关键点也是很好的保留点。

Identifying salient points

The definition of "important" or salient points on a shape is an old and fundamental problem in computer graphics. Important points, which we will term key points, can be used for representing a shape (e.g. as vertices of a polyline or as knots of a spline). Key points that correspond to perceptually salient points are useful as handles for editing. Key points are also good points to retain in simplifying a shape.
