3D CNN visualization

Hi,

I also have a question, do you plan to implement the 3D version to visualize the activation map and decent???

Thanks in advance

We have activation visualization already as part of the functionalities. If you mean for CNNs having 3d inputs as in videos - it would be a cool add on, but we might not be able to come up with that in some near future. Or did you mean something else?

@falaktheoptimist , I am talking about some 3D image inputs, like MRI. That could be cool to visualize the activations and deconv for 3D CNN architecture.

For the 3D visualization, I am not sure if this fits in tensorboard. I think this is not that difficult to implement, we can just save the activation maps as an nifti format.

It would indeed be a cool new application. This should work, although we haven't run this case explicily. The activation maps would be saved as individual grayscale frames in png format - as we haven't added provision for nifti format. If you add that or compute some results - please do share with us or add a PR with your notebook and we'll incorporate that.

@anbai106 Hello, I want to do the visualization work on 3D MRI data as well, in detail, visualizing the feature maps of every conv layers. Have you find any feasible method for that target? Looking forward to your advice.
Do thanks a lot!
