ABSTRACT:
An image processing method for extracting a thread-like structure (GW) represented on the background in a digital noisy original image (IM1,IM0), comprising steps of acquisition (1) of the original image data of one End-Point (P0, Q0) of the threadlike structure and comprising steps of iterative Front Propagation stage (4) starting from the unique End-Point (P0, Q0) and supplying an End-Front (F1, F2) yielding End-Front Points (41); constructing a set of Candidate Paths between the unique End-Point (P0, Q0) and said End-Front Points and selecting (42) one Best Candidate Path for representing the threadlike structure. Application: Medical Imaging; X-ray apparatus with image processing means and display means.
