For 3D activations I just want to verify my understanding. Each filter is very similar to the filters we used before. The main difference however is instead of feature extraction using pre specified image filters we do feature extraction by training the filters as well?

Exactly. The first layer of a CNN represents the set of filters used to extract features from an image, and the filters are chosen by training the CNN.
