Retinal Vessel Diameter Measurement Using Unsupervised Linear Discriminant Analysis
Figure 1
Obtaining the training classes for a sample vessel profile (CLRIS, image no. 1, cross section no. 22). The extremums related to the three classes are shown with asterisks in different colours (Red, Green, and Blue). Blue curves are the regions related to the detected classes. Red curves are the boundaries separating the classes. , , and represent the first three largest angles.
