mindspore.dataset.vision.py_transforms.FiveCrop

class mindspore.dataset.vision.py_transforms.FiveCrop(size)[source]

Crop the given image into one central crop and four corners.

Parameters

size (Union[int, Sequence[int, int]]) – The size of the cropped image. If int is provided, a square of size (size, size) will be cropped with this value. If Sequence[int, int] is provided, its two elements will be taken as the cropped height and width.

Raises

TypeError – If size is not of type int or Sequence[int, int].
ValueError – If size is not positive.

Supported Platforms:: CPU

...                            lambda *images: numpy.stack([py_vision.ToTensor()(image) for image in images])])
>>> # apply the transform to dataset through map function
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
