Math, implementation and accurate interpretation of monai.transforms.Rand3DElastic

[YerePhy]

Hi,

I've search about elastic deformations, in the computer science context not in physics context, but I haven't find a detailed description of how this tranformations are done and the intiuitive idea behind. If someone can explain at least the intuition and point out some references and explain each parameter of monai.transforms.Rand3DElastic (the non-trivial ones) it would be very helpful, or at least a good guess for the parameters.

Thanks.

sure, this paper describes Gaussian filtering over the random displacement fields, it visually resembles elastic deformation https://www.microsoft.com/en-us/research/wp-content/uploads/2003/08/icdar03.pdf

Thanks @wyli!
