Classes

Normalize	Normalize images with the given mean and std value.
RescaleToZeroOne	Transform the images into a range between 0 and 1.

class mmagic.datasets.transforms.normalization.Normalize(keys, mean, std, to_rgb=False, save_original=False)

Bases: mmcv.transforms.BaseTransform

Normalize images with the given mean and std value.

Required keys are the keys in attribute “keys”, added or modified keys are the keys in attribute “keys” and these keys with postfix ‘_norm_cfg’. It also supports normalizing a list of images.

参数

• mean (np.ndarray) – Mean values of different channels.

• std (np.ndarray) – Std values of different channels.

• to_rgb (bool) – Whether to convert channels from BGR to RGB. Default: False.

• save_original (bool) – Whether to save original images. Default: False.
