Fig. 7From: Automated assessment of the smoothness of retinal layers in optical coherence tomography images using a machine learning algorithma Automated calculation of SI, yellow straight line indicates the Euclidean distance between the beginning and the end point of each layer in the final output image (the length of the straight line connecting the start and the end of IPL or OPL) and, green curves shows the actual length of the layers, obtained by calculating the sum of the Euclidean distance between all the pixels that make up the layer. The results of SI calculation in IPL and OPL for patients with mild, moderate, and severe diabetic retinopathy are depicted in b, c and d respectivelyBack to article page
