摘要
In this paper a new method to obtain the Euler number of a binary object via its skeleton is presented. The number of terminal points (points with just one neighbor) and the number of three-edge-points (points with only three neighbors) in the graph are used to obtain this important invariant. As the proposed approach is inherently parallel, the resulting algorithm is very fast.
