Fig. 12From: Retinal status analysis method based on feature extraction and quantitative grading in OCT imagesThe grading results of quantitative data features. Through the quantitative data, combined with the reference model for abnormal grading, the regions and severity of abnormal can be more intuitive to display. As shown, a does not appear abnormal warning. While image b and c show larger abnormal grade and d shows abnormal in curvature and gradient features of RPE. P1, P2, P3, P4, P5 respectively correspond to PE_L, PA_L, Fovea, PA_R, PE_R regionsBack to article page
