mindspore.dataset.vision.RandomAdjustSharpness

class mindspore.dataset.vision.RandomAdjustSharpness(degree, prob=0.5)[source]

Randomly adjust the sharpness of the input image with a given probability.

Parameters
  • degree (float) – Sharpness adjustment degree, which must be non negative. Degree of 0.0 gives a blurred image, degree of 1.0 gives the original image, and degree of 2.0 increases the sharpness by a factor of 2.

  • prob (float, optional) – Probability of the image being sharpness adjusted, which must be in range of [0.0, 1.0]. Default: 0.5.

Raises

>>>
>>> image_folder_dataset = ds.ImageFolderDataset("/path/to/image_folder_dataset_directory")
>>> transforms_list = [vision.Decode(), vision.RandomAdjustSharpness(2.0, 0.5)]
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
