User interface #55
Description
We should have a user interface for some of the possibly interactive parts. It should be fine to have this in a notebook, as that's what users are already familiar with. We should use LiberTEM-panel-ui by @matbryan52 for this purpose.
Ideas about workflows with interactivity:
- Building the aperture
- Include a preview reconstruction for the first hologram in the stack
- FFT view which shows the selected aperture over the FFT of the first frame
- Could also include a slider to preview different frames
- Tweaking the sideband position. Usually the estimated position should work, but the user may want to move it
- Additional mask tweaks, like adding a line filter (or maybe more generally editing the shape of the aperture, if needed)
- Registration and averaging
- Selection of the area/slice on which the registration should be run
- Should be possible to scrub through both the original stack and the aligned stack, and view the averaged result
- Possibly manually adjust single shift vectors where the auto-alignment failed? Can we cross-check the aligned stack with some similarity measure for finding alignment issues?
- Phase unwrapping
- Include a manual phase rotation, for example to move phase jumps out of the sample area
For all of these, it should be possible to extract the interactively determined parameters such that a non-interactive script reproducing the whole reconstruction can be published alongside the original data.
For the interactive use-case, it could pay off to make sure computations happen on the GPU, to get good per-hologram performance for the previews.
