1. A computerized method for detecting retinal abnormalities, comprising:
- receiving, by a computer, an image of a retina;
smoothing and segmenting the image, by the computer, wherein the smoothing and segmenting are interdependent and smoothing and segmenting further comprise;
reducing the value of a first and a second energy function, wherein the first energy function uses a first error metric and the second energy function uses a second error metric different from the first error metric; and
combining information about a first and a second set of smoothing and segmenting parameters obtained by reducing the value of the first and the second energy functions;
identifying, in the smoothed and segmented image, by the computer, at least one retinal feature; and
analyzing, by the computer, the identified at least one retinal feature in the smoothed and segmented image to identify a retinal abnormality.

Abstract
The systems and methods described herein relate generally to the detection of retinal abnormalities. More particularly, the systems and methods are used to analyze a fundus or other image of the retina. In some implementations, the image is analyzed by interdependently smoothing and segmenting the image. Using the smoothed and segmented image, retinal features can be identifying in the image. The systems and methods can then analyze the detected retinal features to identify retinal abnormalities.
