Abstract :
Monitoring measurements of the openness of the major temporal arcade (MTA) and how they change over time could facilitate improved diagnosis and optimized treatment of retinopathy. We present the design of a graphical user interface (GUI) for user-guided modeling and measurement of the openness of the MTA based on a form of the generalized Hough transform for the detection of parabolas. The GUI is being designed in consultation with an expert ophthalmologist and adheres to the main principles of GUI design. The results of the dual-parabolic modeling procedure obtained with 40 images of the DRIVE database, as compared with hand-drawn traces of the MTA, indicate a low mean distance to the closest point of less than 10 pixels (0.2 mm). The proposed methods should facilitate quantitative analysis of the architecture of the MTA and overcome limitations associated with manual analysis.
