HueTransform

class paddle.vision.transforms. HueTransform ( value, keys=None ) [source]

Adjust hue of the image.

Parameters
  • value (float) – How much to adjust the hue. Can be any number between 0 and 0.5, 0 gives the original image.

  • keys (list[str]|tuple[str], optional) – Same as BaseTransform. Default: None.

Shape:
  • img(PIL.Image|np.ndarray|Paddle.Tensor): The input image with shape (H x W x C).

  • output(PIL.Image|np.ndarray|Paddle.Tensor): An image with a transform in hue.

Returns

A callable object of HueTransform.

Examples

>>> import numpy as np
>>> from PIL import Image
>>> from paddle.vision.transforms import HueTransform

>>> transform = HueTransform(0.4)
>>> fake_img = Image.fromarray((np.random.rand(224, 224, 3) * 255.).astype(np.uint8))
>>> fake_img = transform(fake_img)
>>> print(fake_img.size)
(224, 224)
