眼底图像形态参数测定

目的介绍一种能与传统的眼底照相机匹配的眼底图像处理系统的图像形态参数测定方法。方法设计针对眼底视网膜图像形态参数进行自动测量的方法,并用VC 程序实现。结果与结论该系统不仅能测量眼底视网膜图像的视杯、视盘的面积、周长、横径、纵径及纵横径比等参数,同时还能测量眼底血管的线径及角度等形态参数。

Automated measurement of retinal image parameters of shape

Objective To introduce a system for measuring retinal image parameters of shape.Methods To design an algorithm for automatically measuring retinal image shape parameters and to project the results on a computer monitor using the VC program.Results and Conclusion This system could measure the length between any two points in the image and the area,perimeter,transverse and vertical diameters of the optic cup or optic disk.It could also provide the ratio of the area of the optic cup to that of the optic disk and the ratio of the transverse diameter to the vertical diameter of the optic cup or optic disk.
