Image L w and enlarged image (L w ). The input image resulting from the decimal-to-binary conversion of image originating from Figure 5 and multiplying it by the image from Figure 6. The black pixels are not taken into account in the computations. The other pixels indicate the value of tangent inclination angle at the given point of the vessel, showing at the same time the place of its existence.
