A computer method for image analysis of the optic disc is presented. Black and white photographic transparencies of the optic disc were scanned by a scanning television camera. The image was digitized into not more than 4,000 x 4,000 points, each representing a value ranging between 0 and 255 gray levels. The images are depicted in two ways; either in the form of a topographic map (contour) in which the curves join points of identical light intensity, or as a relief that expresses the light intensity of every scanned line. This method emphasizes the qualitative parameters of the disc, and enables a quantitative determination of some disc pathologies.
提出了一种用于视盘图像分析的计算机方法。视盘的黑白摄影透明片由扫描电视摄像机进行扫描。图像被数字化为不超过4000×4000个点，每个点代表一个介于0到255灰度级之间的值。图像以两种方式呈现：要么是以地形图（等高线）的形式，其中曲线连接光强度相同的点，要么是以表示每条扫描线光强度的浮雕形式。该方法强调视盘的定性参数，并能够对视盘的一些病变进行定量测定。
