MESSIDOR (MESSIDOR DATABASE)
收藏资源简介:
Messidor数据库后极的1200个眼底彩色数字图像是由3个眼科使用彩色视频3CCD摄像机获得的,该摄像机安装在具有45度视野的Topcon TRC NW6非散瞳视黄镜上。在1440*960、2240*1488或2304*1536像素处使用每个颜色平面8位捕获图像。 在瞳孔扩张 (0.5% 时滴一滴托吡卡胺) 的情况下获取800图像,并在没有扩张的情况下400。 1200图像包装在3组中,每个眼科部门一个。每个集合被分成4个压缩子集,其中包含TIFF格式的每个100图像和一个Excel文件,每个图像具有医学诊断。
The 1200 color digital fundus images of the posterior pole from the Messidor database were acquired using three color video 3CCD cameras mounted on a Topcon TRC NW6 non-mydriatic retinal camera with a 45-degree field of view. Images were captured with 8 bits per color plane at resolutions of 1440×960, 2240×1488, or 2304×1536 pixels. A total of 800 images were acquired with pupil dilation (one drop of 0.5% tropicamide), while the remaining 400 images were captured without pupil dilation. The 1200 images are packaged into three sets, one for each ophthalmology department. Each set is divided into 4 compressed subsets, each containing 100 images in TIFF format and an Excel file that stores the medical diagnostic information for each individual image.
