Hi, I am interested in that how to use the existed MatConvnet to realize 3D-CNN to learn spatio-temporal Features from Video sequence, as described in following papers? the key step is how to realize 3D-Convoution and 3D-pooling. 3D convolutional neural networks for human action recognition-2013-ICMI; Learning Spatiotemporal Features with 3D Convolutional Networks_2015-ICCV Could you please give an answer?

Hello,

At the comment the library doesn't support convolutions for 3D volumes (X,Y,Z + Channels).

Yes. that's unfortunately correct. However, we are now looking at adding this possibility.
