AL-DIC是一种快速并行计算的DIC算法，它结合了局部子集DIC（快速并行计算）和全局DIC（保证运动兼容性）的优点。

AL-DIC is a fast, parallel-computing DIC algorithm, which combines advantages of Local Subset DIC (fast, compute in parallel) and Global DIC (guarantee kinematic compatibility).

以下列出了AL-DIC算法的一些优点：

Here I list some benefits of AL-DIC algorithm: 

使用了分布式并行计算的快速算法

• Fast algorithm using distributed parallel computing; 

以增广拉格朗日形式将全局运动兼容性作为全局约束，并使用交替方向法的乘子方案实现

• Add global kinematic compatibility as a global constraint in the form of augmented Lagrangian, and implemented using Alternating Direction Method of Multipliers scheme; 

同时关联位移场和仿射变形梯度

• Correlate both displacement fields and affine deformation gradients at the same time; 

不需要大量人为经验来选择位移平滑滤波器

• Don’t need much manual experience of choosing displacement smoothing filters. 

适用于压缩的DIC图像和自适应网格

• Work well with compressed DIC images and adaptive mesh.
