Abstract
A method for improving segmentation in optical coherence tomography imaging. The method comprises obtaining an OCT image of imaged tissue, generating a first feature image for at least a portion of the OCT image, and generating a second feature image for at least the portion of the OCT image, based on either the OCT image or the first feature image, by integrating image data in a first direction across the OCT image or first feature image. A third feature image is generated as a mathematical function of the first and second feature images, and layer segmentation for the OCT image is performed, based on the third feature image.
