SCRFD bounding box scaling

[kkeroo]

Hi,

I am trying to use your pre-trained onnx scrfd_10g model. I also convert it to a .blob file using our internal library to work on edge devices. When running the model, I get scores, bboxes and kps from last layers without a problem. Also, the faces are detected, but bbox layer outputs are values between 0 and 5 or 7. I think they are somehow normalized. I can not figure it out how to transform the coordinates back to the image coordinates (the image size is 640x640). Could you help, please? The same goes for kps.

Thanks!
