Segmentation and identification of layered structures in images

摘要

Disclosed herein are systems and method for segmentation and identification of structured features in images. According to an aspect, a method may include representing an image as a graph of nodes connected together by edges. For example, the image may be an ocular image showing layered structures or other features of the retina. The method may also include adding, to the graph, nodes adjacent to nodes along first and second sides of the graph. The added nodes may have edge weights less than the nodes along the first and second sides of the graph. Further, the method may include assigning start and end points to any of the added nodes along the first and second sides, respectively. The method may also include graph cutting between the start and end points for identifying a feature in the image.

1. A method comprising:
identifying nodes corresponding to a layered feature in an image; determining convex hull coordinates of the nodes; and moving pixel columns of the image up or down until pixels corresponding to a reference line of the convex hull coordinates extend substantially horizontally for flattening the image.
