nvidia.dali.fn.hue(__input, /, *, bytes_per_sample_hint=[0], dtype=None, hue=0.0, image_type=DALIImageType.RGB, preserve=False, seed=-1, device=None, name=None)#

Changes the hue level of the image.

This operator allows sequence inputs and supports volumetric data.

Supported backends
  • ‘cpu’

  • ‘gpu’


__input (TensorList ('HWC', 'FHWC', 'DHWC')) – 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.

  • dtype (nvidia.dali.types.DALIDataType, optional) –

    Output data type.

    If not set, the input type is used.

  • hue (float or TensorList of float, optional, default = 0.0) –

    The hue change in degrees.

    Supports per-frame inputs.

  • image_type (nvidia.dali.types.DALIImageType, optional, default = DALIImageType.RGB) – The color space of the input and the output image.

  • 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.
