Opening detection and correction. (a) I Original , Example of an Image with branch opening. (b) I PreProc consequent preprocessed image with branch opening. (c) Resultant cA1. (d) l polar * Opened the polar lumen object with branch opening. (e) Height of the final polar image represented by signal h(l polar * Opened ), high derivatives highlighted in yellow, indicates the presence of opening. (f) h(l polar * Opened ) with correction being performed, values corresponding to the opening are removed for interpolation. (g) h(l polar * Corrected ), Signal representing the column corrected. (h) The corrected polar lumen object l polar * Corrected .
