Clarification on image augmentations in SSDDefaultTrainTransform

I saw in the code that SSDDefaultTrainTransform provides various augmentation mechanisms like:
random color jitter, random cropping, random flip, etc.

But are these applied by default or is there a way to explicitly call these?
I tried introducing some print statements to see if they are applied, but I did not see any changes in the console.

I am using SSD detection with a custom LST dataset.

Sorry for post, these functions work implicitly.
