Finally, for 3D images, such as videos, magnetic resonance imaging
(MRI) scans, or confocal microscopy, we refer to the leading dimension
as ``frame``, abbreviated as ``frm`` or ``f``. In many cases,
as ``frame``, abbreviated as ``frm`` or ``f``.
These conventions are summarized below:

2D grayscale (row, col)
2D multichannel (eg. RGB) (row, col, ch)
3D grayscale (frm, row, col)
3D multichannel (frm, row, col, ch)

In many cases,
the third imaging dimension has lower resolution than the other two,
and processing must be done frame-wise. When frames are the leading
dimension, we can use the following syntax:
