增广拉格朗日数字量相关性(ALDVC)
自适应拉格朗日数字量相关性——体积位移和应变测量基于混合local-global方法
增广拉格朗日数字量相关性(ALDVC):体积位移和应变测量基于混合local-global方法。ALDVC是一种快速、并行混合"的算法,结合本地优势子集方法(计算速度快和并行计算)和全球有限单元方法(保证全局运动的兼容性,降低噪音)。

ALDVC算法的优势
[1]这是一个快速算法使用分布式并行计算。
[2]全球运动兼容性被添加作为一个全球约束形式的增广拉格朗日函数,并使用乘数的交替方向方法解决方案。
[3]位移场和仿射变形梯度都是在同一时间相关。
[4]不需要太多的人工经验选择位移平滑滤波器。
[5]能够计算与多个图像帧图像序列,尤其非常有用的测量非常大的变形。

% * * * * * *注意* * * * * *
%的“x, y, z”或“1 - 2 - 3——“坐标在ALDVC代码总是对应于第一,第二和第三Matlab工作空间变量的指标。例如,p_meas(: 1)和p_meas(:, 2)的x - y坐标和散点。
%
%这有点不同于一些MATLAB图像处理功能。%为例,如果一个三维图像大小MxNxL,在这段代码中,我们总是有图像size_x = M, size_y = N, L size_z =。如果你使用一些Matlab计算机视觉/图像后处理功能,例如,“imagesc3D”,或“imshow3D”,或“冲浪”,它会读取size_x = N, size_y = M, size_z = L。

%请注意这个区别。
