Thanks for sharing these links. I found https://github.com/aleju/imgaug https://github.com/aleju/imgaug and https://github.com/mdbloice/Augmentor https://github.com/mdbloice/Augmentor to be good when you have 2D data. My challenge is that I have x,y and depth(Z) now all image transformations in colour space can't be applied to depth space so which ones would work best and any pointers on tooling around them would be helpful.

  > all image transformations in colour space can't be applied to depth space Why? If you treat the depth channel as an additional color, you might even be able to use the libraries you mentioned without modification (unless they have hard-coded assumptions on the number of color channels). Depth isn't really special, all the same ideas for data augmentation still apply. You just have to transform it with the rest of the data, so if you e.g. mirror the image, the depth gets mirrored as well.

    But when RGB scales, tilts or shears then how do you mathematically move depth accordingly?
