Optic Disc Segmentation

The cup-to-disc ratio is an important statistic in diagnosing glaucoma. However segmentation must be done manually which is quite tedious and time-consuming. Also there is large variability between specialists. This research is an attempt to apply graph search techniques to the segmentation problem in an attempt to improve upon current pixel classification techniques.

Techniques

  • Pixel Classification
  • Feature Selection
  • Probability Map Computation
  • Cost Function Optimization
  • Convex Shape Segmentation
  • Simultaneous Cup/Disc Segmentation
  • Combining Region-based and Edge-based Information
