- To enable precise eye movement measurements using scanning laser ophthalmoscopy (SLO).
Main Methods:
- Utilized the simplex algorithm to fit the eye's rotational parameters.
- Employed data from individually selected ocular fundus landmarks before and after eye rotation.
- Expressed rotational parameters as a rotation vector and three spherical Euler angles.
Main Results:
- Successfully implemented a computational method for 3D eye rotation specification.
- The method demonstrated the ability to fit rotational parameters using fundus landmarks.
