提高数字体图像相关算法精度和计算效率的方法

摘要

Through the use of the image of a gray scale gradient to calculate the three-dimensional dis-placement field distribution, the research improves the accuracy and efficiency of the displacement using ternary cubic interpolation gray of sub-voxel location.Based on the results of simulation analysis, this pa-per has verified the correctness of the method.%在处理大量数据的情况下，通过利用图像一阶灰度梯度来计算三维位移场分布，采用亚体素位置三元三次灰度插值法来提高位移计算精度和效率。仿真实验验证了该方法的正确性。
