class mindspore.dataset.vision.py_transforms.RandomGrayscale(prob=0.1)

Randomly convert the input image into grayscale with a given probability.

Parameters

prob (float, optional) – Probability of the image being converted to grayscale (default=0.1).

Examples

>>> from mindspore.dataset.transforms.py_transforms import Compose
>>> transforms_list = Compose([py_vision.Decode(),
...                            py_vision.RandomGrayscale(0.3),
...                            py_vision.ToTensor()])
>>> # apply the transform to dataset through map function
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
...                                                 input_columns="image")
