Face bounding box error occurs when an image contains two faces.

I visualized the file FaceID-70K/laion_1024/389.png (see below) and noticed the face bounding box is wrong.

The top-left corner of the image shows the face file from the dataset, visualized directly.

SWHL changed discussion title from face bbox error when a image has two faces to Face bounding box error occurs when an image contains two faces.

I found that when an image contains multiple faces, the provided bbox is likely to be incorrect.
