BrightnessTransform¶

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

Adjust brightness of the image.

Parameters

• value (float) – How much to adjust the brightness. Can be any non negative number. 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 brightness.

Returns

A callable object of BrightnessTransform.

Examples

>>> import numpy as np
>>> from PIL import Image
>>> from paddle.vision.transforms import BrightnessTransform
>>> np.random.seed(2023)

>>> transform = BrightnessTransform(0.4)
>>> fake_img = Image.fromarray((np.random.rand(224, 224, 3) * 255.).astype(np.uint8))
>>> print(fake_img.load()[1,1])
(60, 169, 34)
>>> 
>>> fake_img = transform(fake_img)
>>> print(fake_img.load()[1,1])
