Paper Abstract

Blood vessel images have strongly morphological characteristic as well as complicated backgrounds. However, traditional boundary extraction algorithms rarely utilize the local uniform direction of the pixels in the vascular margin and often incur discontinuities of edges due to background noises. In this paper a new vascular boundary extraction algorithm based on direction filtering is presented, in which some algorithms, such as chaotic filtering, direction and distance matrix, as well as edge tracing, are put forward. The experimental results indicate that the algorithm has achieved better effects in noise depression and vascular extraction.
