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.

A method for improving segmentation in optical coherence tomography (OCT) imaging, the method comprising:
- obtaining an OCT image of imaged tissue;
- generating a first feature image for at least a portion of the OCT image;
- 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;
- generating a third feature image as a mathematical function of the first and second feature images;
- and
- performing layer segmentation for the OCT image, based on the third feature image.
An Optical Coherence Tomography (OCT) imaging apparatus, comprising:
- a communication interface configured to obtain an OCT image of imaged tissue;
- and
- a processing circuit operatively coupled to the communication interface and configured to:
- generate a first feature image for at least a portion of the OCT image;
- generate 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;
- generate a third feature image as a mathematical function of the first and second feature images;
- and
- perform layer segmentation for the OCT image, based on the third feature image.
