Figure 4From: Segmentation and morphological analysis of amyloid fibrils from cryo-EM image dataThree examples of segmented fibrils, showing the (rotated) grayscale image of the fibril (top row), the width of the fibril along its major axis (second row), as well as the mean gray value (third row) and the variance in gray values (bottom row) at each slice orthogonal to the major axis. Each curve is overlaid with an fitted sine function shown in redBack to article page
