ABSTRACT:
The invention provides a method of locating pairs of parallel curved lines in an image, consisting in representing the image in the form of straight line segments, in forming from these segments elementary sections of parallel segments, in assembling together the related elementary sections so as to from vessels or vessel portions and filtering the vessels thus formed for eliminating the parasite vessels.
