物体的骨架是物体形状中包含的最大圆盘中心的轨迹。骨架提供了一个紧凑的表示对象，有用的形状描述和识别。骨架变换的一个众所周知的缺点是它缺乏连续性。本文关注的是建模的噪声，可能会影响对象和后果，这种噪声的骨架。一个图（称为参数图）的介绍，由于噪声的分支的特点。我们从这个初步的研究推导出一种方法来简化骨架。它取决于可以直接在与每个骨架相关联的参数图上选择的阈值。
The skeleton of an object is the locus of the centers of maximal discs included in the shape. The skeleton provides a compact representation of objects, useful for shape description and recognition. A well-known drawback of the skeleton transformation is its lack of continuity. This paper is concerned with the modeling of noise that may affect objects and the consequence of this noise on the skeleton. A graph (called the parameter graph) is introduced, on which branches due to noise are characterized. We deduce from this preliminary study a method to simplify skeletons. It depends on thresholds that can be chosen directly on the parameter graph associated to each skeleton.
