翻译成英文：数据集包含3982张甲骨文图像共有21253个手写甲骨文字符被矩形框标注平均每张图像包含大约6个手写甲骨文字符。本次标注将甲骨文献中出现的手写甲骨文字标为正样本标签为1。从标注字符的角度看文献中的手写甲骨文基本是小目标因此小目标检测是算法设计过程中应予以重点考虑的因素。

The dataset contains 3982 oracle bone images, with a total of 21253 handwritten oracle bone characters annotated with rectangular bounding boxes. On average, each image contains approximately 6 handwritten oracle bone characters. In this annotation, the handwritten oracle bone characters found in the oracle bone literature are labeled as positive samples with a label of 1. From the perspective of annotated characters, the handwritten oracle bone characters in the literature are generally small targets. Therefore, small object detection should be a key consideration in the algorithm design process
