The experiments on many retinal images indicate that this blood vessel extraction method is computational efficient and can extract most blood vessels including very small blood vessels.

多幅视网膜图像的实验证明，该方法的计算速度很快，并且可以提取包括细血管在内的绝大部分血管。

Aiming at the bad performance of existing retinal blood vessel segmentation methods for small and low contrast vessels, a new segmentation method based on transition region extraction is proposed.

针对现有视网膜血管分割方法对于小血管和低对比度血管分割效果差的问题，提出了一种基于过渡区提取的视网膜血管分割方法。
