- class mmcls.datasets.pipelines.Brightness(magnitude, prob=0.5, random_negative_prob=0.5)¶
Adjust images brightness.
magnitude (int | float) – 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.
prob (float) – The probability for performing contrast 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.
