Dataset for "Computer vision assisted decomposition analysis of atom probe tomography data"

Dataset for the article "Computer vision assisted decomposition analysis of atom probe tomography data". APT measurements were performed by Marcus Hans at Materials Chemistry (RWTH Aachen University) using a CAMECA LEAP 4000X HR. Training data was created by Janis A. Sälker.

Content:

- 13 (V,Al)N and 3 (Ti,Al)N APT reconstructions (.epos file format) and the corresponding range file (.rrng file format).

- Training data (images & masks) for 9 labeled (V,Al)N APT samples (h5 file format). Image data with key "image" of shape (2, number_of_slices, 608, 192), where 2 corresponds to the V- and Al-contribution/channel and 608/192 to the height/width of the images. Masks/labels with key "label" of shape (number_of_slices, 608, 192)

本数据集为论文《计算机视觉辅助原子探针断层扫描（Atom Probe Tomography, APT）数据分解分析》的配套数据集。原子探针断层扫描测试由马库斯·汉斯（Marcus Hans）于亚琛工业大学材料化学研究所完成，所用设备为CAMECA LEAP 4000X HR型原子探针断层扫描系统。训练数据集由亚尼斯·A.塞尔克（Janis A. Sälker）构建。

内容：
- 包含13组(V,Al)N与3组(Ti,Al)N的APT重构数据（文件格式为.epos），以及对应的范围文件（文件格式为.rrng）。
- 包含9个已标注(V,Al)N APT样本的训练数据（图像与掩码，文件格式为.h5）：其中图像数据的键名为"image"，形状为(2, 切片数, 608, 192)，维度2对应钒(V)与铝(Al)的信号通道/贡献占比，608与192分别为图像的高度与宽度；掩码/标注数据的键名为"label"，形状为(切片数, 608, 192)
