HDR28K
收藏资源简介:
HDR28K是由华南理工大学创建的大规模历史文档修复数据集,包含28,552对损坏与修复的图像对,具有字符级标注和多风格退化。数据集通过精心设计的退化过程模拟了历史文档中的字符缺失、纸张损坏和墨水侵蚀,旨在真实再现历史文档的损坏情况。数据集的创建过程包括从高分辨率图像中裁剪512×512的图像块,并应用三种退化方法。HDR28K主要应用于历史文档修复任务,旨在通过预测损坏文档的原始外观,解决历史文档修复中的复杂问题,推动文化遗产的保护与传承。
HDR28K is a large-scale historical document restoration dataset created by South China University of Technology. It comprises 28,552 pairs of corrupted and restored images, with character-level annotations and multi-style degradations. The dataset simulates character missing, paper damage and ink erosion in historical documents via carefully designed degradation processes, aiming to authentically reproduce the actual damage conditions of historical documents. The dataset creation process includes cropping 512×512 image patches from high-resolution images and applying three degradation methods. HDR28K is primarily applied to historical document restoration tasks, aiming to address the complex issues in historical document restoration by predicting the original appearance of corrupted documents, thereby promoting the protection and inheritance of cultural heritage.
