Figure 4

Bulk motion artifact removal on two different optical coherence tomographic (OCT) devices. Top row: AngioVue (OptoVue, USA). Bottom row: AngioPlex (Zeiss, Germany). The first column on the left shows the original en face projection of the superficial vascular complex (SVC). The remaining columns show binarization of the raw data (second column), binarization after median subtraction (third column), and after regression-based bulk motion subtraction (last column). Note the prominent horizontal motion artifacts incorporated into the vessel masks created from the original and median-subtracted images (columns 2 and 3) that are removed by the regression-based method (column 4).
