CTFilm20K
收藏资源简介:
CTFilm20K数据集是由中国科学院计算技术研究所创建的首个大规模CT胶片数据库,包含约20,000张图片。该数据集利用Blender软件模拟真实世界中的变形场景,记录了与几何变形和光照变化相关的详细信息,如3D坐标、深度、法线和UV贴图。数据集的创建过程涉及高质量背景图像和CT数据的收集,以及使用逼真的渲染技术生成图像。CTFilm20K数据集主要用于CT胶片恢复研究,旨在解决胶片图像因几何变形和光照变化而导致的质量问题,支持医疗图像分析和远程咨询的需求。
CTFilm20K is the first large-scale CT film database developed by the Institute of Computing Technology, Chinese Academy of Sciences, containing approximately 20,000 images. This dataset utilizes Blender software to simulate real-world deformation scenarios, and records detailed information related to geometric deformations and illumination variations, including 3D coordinates, depth values, normal maps, and UV maps. The construction process of the dataset involves the collection of high-quality background images and CT data, as well as the generation of images via realistic rendering techniques. The CTFilm20K dataset is primarily applied to CT film restoration research, aiming to address the quality issues of film images induced by geometric deformations and illumination variations, and supports the requirements of medical image analysis and remote consultation.
