Image annotation adopts single character annotation, using LabelImg to select the corresponding oracle bone characters on the image. During the selection process, the oracle bone characters should be closely aligned, as shown in Figure 2. The annotation information for each character is the coordinates (x1, y1, x2, y2) of its selected bounding box, where (x1, y1) is the coordinates of the top-left corner of the rectangle, and (x2, y2) is the coordinates of the bottom-right corner of the rectangle
