Example of images obtained during a third part of the proposed method of image analysis and processing. Previous two parts were shown on the Figure 3. The third part is the final part of the calculation of the severity of PEX syndrome. Initially the borders K
(n) are estimated and the contour of PEX (K
(n)) is determined. Based on the obtained data the severity of PEX syndrome is calculated. In some cases, magnifications of image fragments are shown.
