Abstract :
The overall scheme aimed at three-dimensional reconstruction of vascular networks from two X-ray projections relies on the efficient detection of vessels in the image frames. The authors describe an intermediate processing level to control the information issued by low-level procedures. Its role consists of filtering and combining centerlines and contours in such a way that only the relevant vessels are preserved
