mindspore.dataset.vision.py_transforms.Equalize

class mindspore.dataset.vision.py_transforms.Equalize[source]

Equalize the histogram of the input PIL Image.

By applying a non-linear mapping to the input image, it creates a uniform distribution of grayscale values in the output.

Examples

>>> from mindspore.dataset.transforms.py_transforms import Compose
>>>
>>> transforms_list = Compose([py_vision.Decode(),
...                            py_vision.Equalize(),
...                            py_vision.ToTensor()])
>>> # apply the transform to dataset through map function
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list,
...                                                 input_columns="image")
