Upside-down images #336

Good morning. How can I implement processing of upside-down images? Looks like keypoints are the same, so I can't just check them and rotate image. Is there any tool or hint to work with that images?

Thank you.

There is no upside-down face in traning data. So the landmarks are wrong.

Please rotate the image of the upside-down faces to the one like the second image before it is sent to the network.
