nvidia.dali.fn.bb_flip¶
- nvidia.dali.fn.bb_flip(*inputs, **kwargs)¶
Flips bounding boxes horizontaly or verticaly (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 (TensorList) – Input to the operator.
- Keyword Arguments:
bytes_per_sample_hint (int or list of int, optional, default = [0]) –
Output size hint, in bytes per sample.
If specified, the operator’s outputs residing in GPU or page-locked host memory will be preallocated to accommodate a batch of samples of this size.
horizontal (int or TensorList of int, optional, default = 1) – Flip horizontal dimension.
ltrb (bool, optional, default = False) – True for
ltrb
or False forxywh
.preserve (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.
seed (int, optional, default = -1) –
Random seed.
If not provided, it will be populated based on the global seed of the pipeline.
vertical (int or TensorList of int, optional, default = 0) – Flip vertical dimension.
