Posterize

class mmpretrain.datasets.transforms.Posterize(bits=None, prob=0.5, **kwargs)

图像像素化（降低各色彩通道的比特数）

参数:

• bits (int, optional) – Number of bits for each pixel in the output img, which should be less or equal to 8. If None, generate from magnitude_range, see BaseAugTransform. Defaults to None.

• prob (float) – The probability for posterizing therefore should be in range [0, 1]. Defaults to 0.5.

• **kwargs – Other keyword arguments of BaseAugTransform.
