有效亚像素木材CT图像配准
Efficient Sub-pixel Wood CT Image Registration
【摘要】 在利用傅里叶变换的相位相关原理对图像进行配准的基础上,对传统傅里叶变换图像配准算法加以改进,采用由粗到细的金字塔分层配准策略,有效提高了图像配准精度。实验结果证明,该算法配准精度高,速度快,具有很强的鲁棒性。
【Abstract】 In the use of Fourier transform phase correlation image alignment principles of right,based on a improved traditional Fourier transform image registration algorithm can be improved by using the pyramid from coarse to fine hierarchical registration strategy,and high robustness the image with accuracy can be effectively improved.Experimental results show that the algorithm has quasi-precision,high speed,and highly robust.
