Figure 3: Integrated fiber angle and epithelial boundary feature algorithms. Panel A shows a single fiber (green) and epithelial region boundary (red) with one highlighted fiber endpoint. Zoomed versions of panel a are shown in panels b, c and d where individual image pixels are represented as filled circles. The nearest distance from to the boundary is indicated in panel B, intersection between the endpoint extension line and the boundary is shown in panel C and the quadratic curve fit to the boundary at the intersection point and tangent line are shown in panel D
