Brightness

class mmpretrain.datasets.transforms.Brightness(magnitude=None, prob=0.5, random_negative_prob=0.5, **kwargs)[source]

Adjust images brightness.

Parameters:
  • magnitude (int | float | None) – The magnitude used for adjusting brightness. A positive magnitude would enhance the brightness and a negative magnitude would make the image darker. A magnitude=0 gives the origin img. If None, generate from magnitude_range, see BaseAugTransform. Defaults to None.

  • prob (float) – The probability for performing brightness adjusting therefore should be in range [0, 1]. Defaults to 0.5.

  • random_negative_prob (float) – The probability that turns the magnitude negative, which should be in range [0,1]. Defaults to 0.5.

  • **kwargs – Other keyword arguments of BaseAugTransform.
