Multi-scale angiography filters: techniques today

Abstract

Vessel enhancement and extraction in Angiography is still in developing state as many important problems still remain to be solved. The computation procedure of vessels in angiography is a very important due to limited computational resources. Computational procedure based on multi-scale has received considerable attention from scientists. Multiscale approaches perform enhancement based on ima g e resolutions and structure sizes. Many contributions have been made on the problem of vessel enhancement multiscale computing of volume data sets but there has never been a head to head evaluation of these approaches. In this paper the various multi-scale vessel enhancement approaches are put in perspective through a head to head comparison of algorithms of the existing research and a generic framework for linear multiscale is presented.
