Top issue.
Some images that contributors send us are not correctly oriented (they may be rotated to the left, to the right or top-down).
Using Google Cloud Vision, we store the orientation of each detected word (up, right, down, left) as a prediction, in the
prediction
DB table, with theimage_orientation
type.prediction.data
has the following structure:{"count":{"up":4,"left":1,"right":18},"rotation":270,"orientation":"right"}
The
count
field gives you how many words were correctly oriented ("up"), left-oriented ("left"), right-oriented ("right"), or flipped ("down").The orientation with the highest count determines the values for the remaining fields:
orientation
gives you the predicted image orientationrotation
gives you the rotation to apply to get a correctly oriented imageWe would like to automatically rotate incorrectly-rotated images if we're confident enough that the rotation is incorrect:
