class mindspore.dataset.vision.RandomInvert(prob=0.5)

Randomly invert the colors of image with a given probability.

Parameters

prob (float, optional) – Probability of the image being inverted, which must be in range of [0.0, 1.0]. Default: 0.5.

Raises

• TypeError – If prob is not of type float.

• ValueError – If prob is not in range [0.0, 1.0].

• RuntimeError – If given tensor shape is not <H, W, C>.

Supported Platforms:

Examples

>>> import mindspore.dataset as ds
>>> import mindspore.dataset.vision as vision
>>>
>>> image_folder_dataset = ds.ImageFolderDataset("/path/to/image_folder_dataset_directory")
>>> transforms_list = [vision.Decode(), vision.RandomInvert(0.5)]
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
...                                                 input_columns=["image"])
