mindspore.dataset.vision.c_transforms.HWC2CHW

class mindspore.dataset.vision.c_transforms.HWC2CHW[source]

Transpose the input image from shape <H, W, C> to shape <C, H, W>. The input image should be 3 channels image.

Note

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

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

Supported Platforms:: CPU Ascend GPU

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