Abstract
Techniques for retinal layer segmentation are presented. The techniques include obtaining current optical coherence tomography (OCT) data for a retina; generating an estimated current en face image based on the current OCT data and an estimated current retinal layer segmentation; determining a registered previous retinal layer segmentation based on a previous retinal layer segmentation, a previous en face image, the estimated current en face image, and the estimated current retinal layer segmentation; updating the estimated current retinal layer segmentation using a deep neural network and based on the current OCT data and the registered previous retinal layer segmentation; repeating the generating, the determining, and the updating to obtain a current retinal layer segmentation as the estimated current retinal layer segmentation; and outputting a property of the retina determined at least in part from the current retinal layer segmentation.
