According to the matching differences cased by cardiac non-rigid motion between angiographic images before and after injected in subtract angiography which is most widely used in diagnosis, a new algorithm based on à trous wavelet of rotary Gaussian with adaptive space coefficient and segmentation based on transition region is put forward to in this(More)
Aiming at the complex background of coronary angiograms, weak contrast between the coronary arteries and the background, a new segmentation method based on transition region extraction is proposed. Firstly, we construct 6 different Gaussian templates that are used to enhance the coronary angiograms. Then the transition region is extracted by using local(More)
