Abstract
This paper introduces a fast centerline extraction method for the cardiovascular virtual endoscopy system. It is based on the current distance mapping algorithm but significantly enhances it. Our method consists of three major parts: image preprocessing and segmentation, euclidean distance transform (EDT) and centerline extraction using pairing heap. The main contribution is the extraction process, we adopt an improved method based on Dijkstra algorithm proposed by Ming Wang and use a new data structure called "pairing heap" to improve this method, and it can speed up the extraction process greatly. The experimental results show that our method is more efficient compared with existing methods. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
