一种基于先验知识的视网膜血管宽度测量方法
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 1
Abstract
利用已获得的血管网络分割结果，提出了一种基于先验知识的视网膜血管宽度测量方法。该方法结合血管骨架的空间位置信息和方向信息，采用改进的定向局部对比度方法检测出骨架线两侧的血管边界像素，从而计算出骨架线上各像素点的血管直径宽度，实验对不同形态结构的血管段进行了仿真，结果证明了该方法的有效性。

Study on corrosion mechanism of RH immersion tube castable
Corrosion mechanism of RH immersion tube castable is yet to be revealed due to few studies on the reactions between RH immersion tube castable and molten slag. In this paper, according to the phase equilibrium theory and...
Eigen-sensitivity analysis of flexible plane induced by fluid medium
The influence of fluid flow induced by vibration of light-density, low-stiffness flexible structure is not negligible. The eigen-sensitivity analysis of vibration should also take the influence of this fluid flow into co...
