Hi, @team, the competition introduction said that every patch may be rotated in [0,180]. Questions: (1) the rotation angles can be only two values: 0 or 180, or any values between 0 and 180? (2) the rotation orientation is only upside-down flipped, or also can be horizontal left-right flipped?
(3) About the positions, after you shuffled the positions of patches horizontally, have you also moved them a little up or down, or not?
May you clarify it?
Hello @stonekingxk,
Thank you for reaching out with your questions. Let me clarify:
- The rotation angles are limited to just 0 or 180 degrees, without any intermediate angles.
- We apply rotations only at 0 or 180 degrees; there are no flipping operations involved. Please note that rotation and flipping are distinct operations when it comes to handling arrays.
- We divide the image into patches incorporating a vertical offset (there’s no horizontal offset). You can observe this arrangement in the plot provided in the starter notebook, after which we proceed to shuffle them.
I hope this clears up any confusion. If you have any more questions, feel free to ask.
Best regards,
Onwards Team
