Can I set a independent probability in the RandomAffine?

[Bigsealion]

I hope the scales, degrees, and translation will be applied in independent probability, but I only find a args p in RandomAffine, but not like the arg flip_probability in RandomFlip.

Now, I tried to do this in the following code (I hope this is right):

tio.Compose([
    tio.RandomAffine(scales=[0.8, 1.2], degrees=0, translation=0, p=0.5),
    tio.RandomAffine(scales=[1, 1], degrees=30, translation=0, p=0.2),
    tio.RandomAffine(scales=[1, 1], degrees=0, translation=10, p=0.3),
])

But I want to know, have any native way to do this?

Thanks!

Hello
no this is not implemented, not sure though why you want this.
A random affine is a mixture of scaling rotation and translation .... and since rotation for instance randomly choose an angle between 0 and 30, there will be cases were there is almost no rotations

your proposed solution will work, but then be aware that you are performing 3 interpolation (so more bluring than only one interpolation) (this may be important ... or not depending on the application)
