Oracle Bone Character Dataset: 3982 Images with 21253 Annotated Characters

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.
