Is 3-dimensional autoencoder for voxel data possible in caffe? #3764

Hi everyone.

I am a newbie in caffe and deep learning. Now I am going to train an convolutional autoencoder for medical voxel data (250 * 250 * 250). But I am not certain about few things. I would appreciate any helpful answers and advises.

  1. Is 3-d convolutional layer available in caffe?
  2. Is 3-d pooling layer available in caffe?
  3. If the answer to 1 or 2 is no, then how difficult would it be for me to implement a 3d layer myself? Should I turn to other frameworks like theano? (I think theano should be capable of 3d layers but it's way too complex to implement it.)

Besides, I have seen someone said that channel could be used as third dimension. Is that correct for such 250^3 voxel data?

Thank you!
