The extraction of contrast-filled vessels from X-ray coronary
angiography(XCA) image sequence has important clinical significance for
intuitively diagnosis and therapy. In this study, XCA image sequence O is
regarded as a three-dimensional tensor input, vessel layer H is a sparse
tensor, and background layer B is a low-rank tensor. Using tensor nuclear
norm(TNN) minimization, a novel method for vessel layer extraction based on
tensor robust principal component analysis(TRPCA) is proposed. Furthermore,
considering the irregular movement of vessels and the dynamic …
