Abstract: Generating a correction algorithm includes obtaining a model of an eye, the model including a front portion with optics to mimic a cornea and a lens of a human eye, and a rear portion having a generally hemispherical-shaped body to mimic a retina of the human eye. The rear portion includes physical reference lines on an inside surface of the generally hemispherical-shaped body. Images of the model are captured using an image capturing device aimed at the model. Vertices of the physical reference lines are identified according to a given projection technique for displaying generally hemispherical-shaped body in a two-dimensional image in the captured images. Idealized placement of the vertices of the physical reference lines is obtained according to the given projection technique. The result is a correction algorithm used to adjust any pixel of an image of an actual eye in the x-axis and in the y-axis.

The captured image of the choroid may be provided to a machine learning system. Indices associated with the image to may be identified based on an output of the machine learning system.
