A Simulated Atomic-resolution HAADF STEM Imaging Dataset Containing Unique ICSD Structure Prototypes

The atomagined dataset is a collection of atomic-resolution images of unique ICSD structure prototypes, simulated in the high angle annular dark field (HAADF) STEM modality. All images are calculated using PRISM imaging software, and post-processed to emulate noise and distortion conditions common to the HAADF STEM imaging mode. The dataset is structured as both a testbed for the development of image retrieval tools in atomic-resolution materials microscopy, containing a designated retrieval dataset with targets/choices splits, as well as a repository for general atomic-resolution HAADF image simulation data with structure projection-based peak position suggestions.atomagined数据集是一套涵盖独特ICSD（无机晶体结构数据库，Inorganic Crystal Structure Database）结构原型的原子分辨率图像集合，基于高角环形暗场（HAADF）扫描透射电子显微镜（STEM）成像模式进行模拟。所有图像均通过PRISM成像软件计算生成，并经过后处理以还原HAADF STEM成像模式中常见的噪声与畸变场景。该数据集兼具双重定位：一方面可作为原子分辨率材料显微学领域图像检索工具开发的测试平台，内置带有目标/候选样本划分的专属检索数据集；另一方面亦可作为通用原子分辨率HAADF图像模拟数据的存储库，配套提供基于结构投影的峰位参考建议。
