Figure 3.

The effect of image quality on manual, semiautomatic, and automatic measurements. Manual segmentation is shown on the OCT-A images of the superficial plexus marked with red dots. Subject JC_10567 had similar image quality between images and had a corresponding similarity between all methods. A large motion artifact is present in the second image from JC_10580, which has a greater effect on the semiautomatic segmentation than the manual or automatic segmentation. The second image from JC_10585 exhibited decreased contrast that affected all methods, though the automatic segmentation appeared most severely affected.
