ShiftTime

class deepinv.transform.ShiftTime(*args, padding='reflect', **kwargs)

Bases: Transform

Shift a video in time with reflective padding.

Generates n_trans randomly transformed versions.

See deepinv.transform.Transform for further details and examples.

Parameters:

• n_trans (int) – number of transformed versions generated per input image.

• padding (str) – "reflect" performs reflective padding, "wrap" performs wrap padding (i.e. roll)

• rng (torch.Generator) – random number generator, if None, use torch.Generator(), defaults to None

roll_reflect_1d(x, by=0, dim=0)

Roll in one dimension with reflect padding.

Parameters:

• x (torch.Tensor) – input image

• by (int) – amount to roll by, defaults to 0

• dim (int) – dimension to roll, defaults to 0
