RandomVerticalFlipOp class

Randomly flips a tensor top-to-bottom with configurable probability.

Useful for data augmentation in tasks where vertical orientation is not semantically important (e.g., satellite imagery, medical imaging).

Supports 3D [C, H, W] and 4D [N, C, H, W] tensor formats.

Equivalent to PyTorch's torchvision.transforms.RandomVerticalFlip(p) or TensorFlow's tf.image.random_flip_up_down().

Complexity

Let N = batch, C = channels, H = height, W = width.

  • Time: O(N × C × H × W) when flip occurs, O(1) when skipped (returns clone).
  • Space: O(N × C × H × W) for output buffer.
