Thank you for the PR.
I don't think we should merge this change. Because currently keras-vis (i.e., master branch) is able to visualize cam in 3-dims.
Indeed it calculates 3dims. But there is a minor bug in the output to handle 3d grayscale images.

Can you show us the detail of minor bug ?
I don't have the error anymore, but if you run the code on a 3D model with 1 channel (batch_size, d1, d2, d3, channel=1), the error will appear.
The solution I proposed is just to adjust the output of as visualize_cam_with_losses folows:

I tried it but the error was not occurred.
The shape of input data is (batch_size, d1, d2, d3, 1) and the shape of visualize_cam
result is (d1, d2, d3), It has no problem.
Can you post the short script (or the link of Gist) here that can reproduce your issue ?

Please resend the images if you need.
We should just fix the issue that causes his use-case to not work. The API should handle N-dim inputs.
This PR adds saliency3D.py, which implements a 3D version of visualize_cam().
Usage is described in example/3D_saliency_snippet.ipynb
A minor change in scipy/misc/pilutils.py is needed and is described in vis/visualization/follow_this.txt
