摘要: We present a new method, based on curve evolution, for the reconstruction of 3D from two different projections. It is minimization an energy functional. Following work geodesic active contours by Caselles et al. (in Int. Conf. Pattern Recognition, 1996, Vol. 43, pp. 693–737), we then transform problem minimizing functional into computation in Riemann space. The Euler-Lagrange equation this derived and its associated PDE solved using level set formulation, giving existence uniqueness results. apply model to vessel biplane angiography.
