Translate¶
- class mmpretrain.datasets.transforms.Translate(magnitude=None, pad_val=128, prob=0.5, direction='horizontal', random_negative_prob=0.5, interpolation='nearest', **kwargs)[source]¶
Translate images.
- Parameters:
magnitude (int | float | None) – The magnitude used for translate. Note that the offset is calculated by magnitude * size in the corresponding direction. With a magnitude of 1, the whole image will be moved out of the range. If None, generate from
magnitude_range
, seeBaseAugTransform
.pad_val (int, Sequence[int]) – Pixel pad_val value for constant fill. If a sequence of length 3, it is used to pad_val R, G, B channels respectively. Defaults to 128.
prob (float) – The probability for performing translate therefore should be in range [0, 1]. Defaults to 0.5.
direction (str) – The translating direction. Options are ‘horizontal’ and ‘vertical’. Defaults to ‘horizontal’.
random_negative_prob (float) – The probability that turns the magnitude negative, which should be in range [0,1]. Defaults to 0.5.
interpolation (str) – Interpolation method. Options are ‘nearest’, ‘bilinear’, ‘bicubic’, ‘area’, ‘lanczos’. Defaults to ‘nearest’.
**kwargs – Other keyword arguments of
BaseAugTransform
