nvidia.dali.fn.water¶
- nvidia.dali.fn.water(*inputs, **kwargs)¶
Performs a water augmentation, which makes the image appear to be underwater.
- Supported backends
‘cpu’
‘gpu’
- Parameters:
input (TensorList ('HWC')) – Input to the operator.
- Keyword Arguments:
ampl_x (float, optional, default = 10.0) – Amplitude of the wave in the x direction.
ampl_y (float, optional, default = 10.0) – Amplitude of the wave in the y direction.
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.
freq_x (float, optional, default = 0.049087) – Frequency of the wave in the x direction.
freq_y (float, optional, default = 0.049087) – Frequence of the wave in the y direction.
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.
phase_x (float, optional, default = 0.0) – Phase of the wave in the x direction.
phase_y (float, optional, default = 0.0) – Phase of the wave in the y direction.
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.
