We study parameterisation-independent closed planar curve matching as a
Bayesian inverse problem. The motion of the curve is modelled via a curve on
the diffeomorphism group acting on the ambient space, leading to a large
deformation diffeomorphic metric mapping (LDDMM) functional pena
建立可靠的对应关系对于 3D 和 2D3D 对准等任务至关重要。为了解决大变形、尺度不一致和模糊匹配问题所带来的挑战,本文引入了一种用于建立鲁棒对应关系的扩散匹配模型,在双随机矩阵空间内将对应估计视为去噪扩散过程,逐步去噪(细化)双随机匹配矩阵至准确的匹配矩阵,以进行高质量的对应估计。该方法在 3D 和 2D3D 对准任务上的评估验证了其有效性。
