nvidia.dali.fn.sphere — NVIDIA DALI (original) (raw)

nvidia.dali.fn.sphere(__input, /, *, bytes_per_sample_hint=[0], fill_value=0.0, interp_type=DALIInterpType.INTERP_NN, mask=1, preserve=False, device=None, name=None)#

Performs a sphere augmentation.

Supported backends

• ‘cpu’
• ‘gpu’

Parameters:

__input¶ (TensorList ( 'HWC' )) – 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.
• fill_value¶ (float, optional, default = 0.0) – Color value that is used for padding.
• interp_type¶ (nvidia.dali.types.DALIInterpType, optional, default = DALIInterpType.INTERP_NN) – Type of interpolation used.
• mask¶ (int or TensorList of int, optional, default = 1) –
  Determines whether to apply this augmentation to the input image.
  Here are the values:
  • 0: Do not apply this transformation.
  • 1: Apply this transformation.
• preserve¶ (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.
