Supporting data for “Out-of-focus 3D Alignment for Digital Holography”

The objective of this research is to assess the repeatability of alignment in actual images captured using a digital holographic system. The image data set consists of recordings of an object with varying translations in 3D space, where the desired motion is recorded using a manual tuning stage. To evaluate the repeatability, two pairs of images are selected for alignment, and their alignment quality is then compared against a ground truth reference.本研究旨在评估采用数字全息系统（digital holographic system）采集的实拍图像的配准可重复性。本图像数据集包含对在三维空间中呈现不同平移位移的物体的录制样本，其目标运动通过手动调节台（manual tuning stage）完成并记录。为评估配准可重复性，研究选取两组图像对进行配准，并将其配准质量与真值参考（ground truth）进行对比。
