We demonstrate that shape contexts can be used to quickly prune a search for similar shapes. We present two algorithms for rapid shape retrieval: representative shape contexts, performing comparisons based on a small number of shape contexts, and shapemes, using vector quantization in the space of shape contexts to obtain prototypical shape pieces.
我们证明形状上下文可用于快速删减对相似形状的搜索。我们提出了两种用于快速形状检索的算法：代表性形状上下文，基于少量形状上下文进行比较；以及形状元，在形状上下文空间中使用矢量量化来获得原型形状片段。
