randall-lab/INRIA-CopyDays

Copydays数据集是为了评估复制检测和近似重复图像检索算法而设计的。它包含了经过各种修改的图像，用于测试检索系统的鲁棒性。数据集分为两种类型的图像：原始图像和强烈修改过的图像。数据集的划分包括查询图像和用于检索的数据库图像。

The Copydays dataset is designed for evaluating copy detection and near-duplicate image retrieval algorithms. It contains images with various modifications to test the robustness of retrieval systems, including both original and strongly modified images. The dataset is split into query images and database images for retrieval purposes.
