mindspore.dataset.vision.AdjustSaturation
- class mindspore.dataset.vision.AdjustSaturation(saturation_factor)[source]
Adjust the saturation of the input image.
- Parameters
saturation_factor (float) – How much to adjust the saturation, must be non negative.
0
gives a black image,1
gives the original image while2
increases the saturation by a factor of 2.- Raises
TypeError – If saturation_factor is not of type float.
ValueError – If saturation_factor is less than 0.
RuntimeError – If shape of the input image is not <H, W, C>.
RuntimeError – If channel of the input image is not 3.
- 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.AdjustSaturation(saturation_factor=2.0)] >>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list, ... input_columns=["image"])
