Measuring regionprops without images

[yfukai]

If I understand correctly, the Image layer is a necessary input for nsr.regionprops_table_all_frames. I think it may be useful to add an option to measure the regionprops without the image layer input (by making the argument Optional). In particular, this feature is necessary for cases where we track segmented regions in a label layer by napari-laptrack.

Hi @yfukai ,

good point! We actually have a function for this recently implemented by @zoccoler . It just doesn't support timelapse data yet. (Full example)

measurements = measure_labels(label_image_reference=cell_labels)

We could easily make it timelapsable using this code snippet (source):

regionprops_table_all_frames = analyze_all_frames(regionprops_table)

Thanks for the feedback!

Best,
Robert
