full-scrolls
收藏资源简介:
该数据集名为full-scrolls,专门为维苏威挑战赛的赫库兰尼姆卷轴提供纤维取向方向场预测数据,旨在作为VC3D中Surface Growth纤维方向优化模块的输入,以帮助分割管道更准确地追踪单个纸莎草纸层。数据内容包括针对每个卷轴CT体积的256x256x256体素立方体预测的纤维取向向量(法向、垂直和水平三个分量),这些预测由Joseph Balmaceda基于维苏威挑战赛纤维骨架数据集训练的小型3D U-Net模型生成,模型在保留数据上的平均性能为|cos(angle)|=0.807(1.0表示完美)。数据集覆盖Scroll 2、3、4和5,其中Scroll 5部分区域已有预计算数据,而Scroll 1仅作为支架结构。数据以瓦片形式存储,每个瓦片文件夹包含Zarr数组文件和meta.json配置文件,整体文件夹结构遵循VC3D volpkg标准,适用于古文书数字化、卷轴层分割和纤维结构分析等任务。
The dataset, named full-scrolls, provides fiber orientation direction field prediction data specifically for the Herculaneum scrolls in the Vesuvius Challenge. It is organized according to the VC3D volpkg folder structure and serves as input for the Surface Growth fiber direction optimization module in VC3D, aiding the segmentation pipeline in more accurately tracking individual papyrus layers. The data includes predicted fiber orientation vectors for 256x256x256 voxel cubes from each scrolls CT volume, with normal, vertical, and horizontal components. These predictions are generated by a small 3D U-Net model trained by Joseph Balmaceda based on the Vesuvius Challenge fiber skeleton dataset, with an average performance of |cos(angle)|=0.807 on held-out data (1.0 indicates perfection). The dataset covers Scrolls 2, 3, 4, and 5, with pre-computed direction fields available for parts of Scroll 5, while Scroll 1 serves only as a scaffold structure. Data is stored in tile format, with each tile folder containing Zarr array files and a meta.json configuration file, following the VC3D volpkg standard. It is suitable for tasks such as ancient document digitization, scroll layer segmentation, and fiber structure analysis.

数据集简介
该数据集包含维苏威挑战赛(Vesuvius Challenge)中赫库兰尼姆古卷(Herculaneum scrolls)的纤维取向方向场,组织结构与VC3D volpkg文件夹结构完全一致。该数据集由Joseph Balmaceda基于维苏威挑战赛纤维骨架数据集训练的小型3D U-Net模型生成。
数据内容
每个瓦片包含256×256×256体素立方体的预测纤维取向向量(包括法向、垂直、水平分量),作为VC3D表面生长纤维方向优化槽的输入,帮助分割管线更准确地追踪单个纸莎草纸层。
- 模型在保留数据上的性能:平均|cos(角度)| = 0.807(1.0为完美,0.5为随机)
- 此为基线/概念验证模型,非生产级模型
