弹性成像中光流估计的挑战
Challenges for Optical Flow Estimates in Elastography
摘要：
在本文中，我们认为可视化的位移场通过光流方法在弹性实验组成的静态压缩的样品。我们提出了一种弹性成像光流法（EOFM），它考虑到实验的约束条件，如适当的边界条件，使用散斑信息，以及包含来自知识的背景材料的结构信息。我们提出的数值模拟和实验数据的基础上，从弹性成像实验，以证明我们所提出的方法的相关性。
英文摘要：
In this paper, we consider visualization of displacement fields via optical flow methods in elastographic experiments consisting of a static compression of a sample. We propose an elastographic optical flow method (EOFM) which takes into account experimental constraints, such as appropriate boundary conditions, the use of speckle information, as well as the inclusion of structural information derived from knowledge of the background material. We present numerical results based on both simulated and experimental data from an elastography experiment in order to demonstrate the relevance of our proposed approach.
