question about train data annotation receipt_00734.json

hi, @ClovaAIAdmin
I feel confused about annotation of train-00734.json.

The height of image is 576, why the annotation is 578?

AFAIK, the coordinates can be outside of the image. This may be because data labeling tools are designed that way. We usually address this issue in the following way: After projecting the coordinates outside the image onto the edges of the image, a new quadrilateral is created based on the coordinates. You can use the new quadrilateral.
