Measuring the Ocular Morphological Parameters of Guinea Pig Eye with Edge Detection and Curve Fitting

Figure 3

(a, b) The eyeball of the selected guinea pig was placed cornea upside (a) and cornea left (b) on the center of the platform. A point was marked by a glowing needle tip at the top of the corneoscleral limbus for location (red arrow). The eyeball was photographed to obtain the coronal and transverse views in this way. The white-black ocular images in the coronal (c) and transverse views (d). (e, f) The points at which image brightness changed sharply were organized into a set of curved line segments termed edges (red points).
