Cone photoreceptor inner segments visualized in non-confocal split-detection adaptive optics scanning light ophthalmoscope (AOSLO) images appear as obliquely illuminated domes with bright and dark opposing regions. Previously, the pairing of these bright and dark regions for automated photoreceptor identification has necessitated complex algorithms. Here we demonstrate how the merging of split-detection images captured with a non-confocal quadrant light detection scheme allows automated cone identification using simple, open-source image processing tools, while also improving accuracy in both normal and pathologic retinas.
在非共焦分裂检测自适应光学扫描激光检眼镜(AOSLO)图像中可视化的视锥光感受器内节呈现为倾斜照明的圆顶,有明暗相对的区域。此前,为了自动识别光感受器而对这些明暗区域进行配对需要复杂的算法。在此,我们展示了如何通过合并使用非共焦象限光检测方案捕获的分裂检测图像,利用简单的开源图像处理工具实现视锥细胞的自动识别,同时还提高了正常和病理视网膜的识别准确性。
