• img

Added Keys:

• img_norm_cfg

  • mean

  • std

  • to_rgb

参数

• mean (sequence) – Mean values of 3 channels.

• std (sequence) – Std values of 3 channels.

• to_rgb (bool) – Whether to convert the image from BGR to RGB before normlizing the image. If to_rgb=True, the order of mean and std should be RGB. If to_rgb=False, the order of mean and std should be the same order of the image. Defaults to True.
