Results of the proposed method for retinal vessel width estimation using the DoG-L7, DoG-L8, and Hermite models in the KPIS and VDIS datasets from REVIEW.

Four evaluation schemes are presented: cross-validation in each dataset (Cv_d) and in the whole REVIEW (Cv_R) and leave-one-segment-out in each dataset (Lso_d) and in the whole REVIEW (Lso_R). O1, O2 and O3 are the observers, and G.T. is the ground truth, i.e., mean of the 3 observations. SR is the success rate, μmeas and σmeas are the mean and standard deviation of the width measurements, respectively, and μerror and σerror are the mean and standard deviation of the measurement errors. * SR values are negatively influenced by errors found in the observers’ annotations.
