Since a skeleton pixel should be in the middle point of one of a pair object boundary, based on the discussion of some commonly used thinning algorithms, a fast thinning algorithm based on midpoints of multi-orientation slices was put forward.

• 在对几种常用细化算法进行探讨之后,提出了利用骨架上的像素点至少在某个方向上应处于该方向对象边界的中心点处的特点,从多个方向对细化对象进行切片,并利用这些切片中心点集作为原始数据集,以快速产生对象骨架的方法。
