Parameters
  • 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.
