Registration method for cross-sectional images of ocular fundus considering eye movement

Abstract

We propose a registration method for cross-sectional images to reconstruct three-dimensional shape of ocular fundus. Scanning lines to obtain cross-sectional images by an Optical Coherence Tomography are displaced caused by eye movement. In the proposed method, we register for cross-sectional images using parameters of Rol-l-Pitch-Yaw rotations to consider eye movement. In addition, we apply objective function considering shape of a disc to accurate reconstruction of ocular fundus. To evaluate the proposed method, registration results demonstrates visualization of the three-dimensional shape of ocular fundus.
