It can be noticed that approximate contour lines are in good agreement with those computed with (11) and the circle assumption holds even in the near vicinity of line conductors.
This procedure requires an initial approximate contour (about 10 points per slice) generated manually.
After the preprocessings, only approximate contours remain from the discrete broken curves, therefore connection operation has to be performed subsequently for the existing break points, and then the contours can be extracted finally.
