mindspore.dataset.vision.HWC2CHW

class mindspore.dataset.vision.HWC2CHW

Transpose the input image from shape <H, W, C> to <C, H, W>. If the input image is of shape <H, W>, it will remain unchanged.

Note

This operation supports running on Ascend or GPU platforms by Offload.

Raises

RuntimeError – If shape of the input image is not <H, W> or <H, W, C>.

Supported Platforms:

CPU

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.RandomHorizontalFlip(0.75),
...                    vision.RandomCrop(512),
...                    vision.HWC2CHW()]
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
...                                                 input_columns=["image"])
