Direct count ROIs

This dataset contains 22 confocal and 22 split detection ROIs where the rod mosaic was completely visualized. These data correspond to Figures 3, 4, and 6 as well as Table 2. There are 22 rod coordinate files that were used to provide direct estimates of rod density (by counting every visible rod in the image) in addition to spacing-derived estimates of rod density. There are 176 cone coordinate files, 44 from each grader (1-4), labeled as either count 1 or count 2. Cone coordinates from grader 1 count 1 were used to compare direct rod density estimates to spacing-derived rod density estimates in Fig. 4.

本数据集包含22幅共聚焦成像及22幅分离检测的感兴趣区域（Region of Interest），其中视杆细胞镶嵌（rod mosaic）结构均完整显现。本数据集对应图3、图4、图6及表2。本数据集包含22份视杆细胞坐标文件，除可通过间距推导得到视杆细胞密度估算值外，还可用于直接估算视杆细胞密度——即通过计数图像中所有可见的视杆细胞。本数据集另有176份视锥细胞坐标文件，其中标注者1至4各提供44份，所有文件均标记为count 1或count 2。标注者1的count 1组视锥细胞坐标文件，被用于在图4中对比直接估算的视杆细胞密度与基于间距推导的视杆细胞密度估算值。
