Multi-dimensional images

[tischi]

Currently it looks like this:

And there also is this:

Personally, while technically correct, I find the concept that a 3-D image could be XYC or XYT or XYZ a bit too technical for this purpose. And if we wanted to speak this language and I think then there should be also 4-D and 5-D images and all the possible permutations that could mean.

What about keeping them as separate concepts:

• Spatial dimensions: 2-D or 3-D
• Time dimension: time
• Channel dimension: channel

So the current Display of 3D images (channels) would become Display of 2D multi-channel images.

And for Display of 3D images (time, volume) I would probably make this separate Topics:

Display of 3-D images:

• Ortho-slicing
• Volume rendering
• 3-D animation (rotation, zoom)

Display of time-lapse images:

• Videos
• 2-D time-lapse animation
• 3-D time-lapse animation

I know though that this is a huge debate and, e.g., the napari folks prefer to just want to speak about N-D arrays without attaching any semantics to the axes. So I am hot sure how to deal with this in this curriculum.

I think currently most image viewer and analysis software do make a clear distinction between X,Y,Z,T,C and thus I would lean towards also making this distinction.
