nvidia.dali.experimental.dynamic.bb_flip(

input,

/,

*,

batch_size=None,

device=None,

horizontal=None,

ltrb=None,

vertical=None,

)

Flips bounding boxes horizontally or vertically (mirror).

The bounding box coordinates for the input are in the [x, y, width, height] - xywh or [left, top, right, bottom] - ltrb format. All coordinates are in the image coordinate system, that is 0.0-1.0

Supported backends

• ‘cpu’

• ‘gpu’

Parameters:

input (Tensor/Batch) – Input to the operator.

Keyword Arguments:

• horizontal (int or Tensor/Batch of int, optional, default = 1) – Flip horizontal dimension.

• ltrb (bool, optional, default = False) – True for ltrb or False for xywh.

• vertical (int or Tensor/Batch of int, optional, default = 0) – Flip vertical dimension.
