Hello everyone,

i started using the Image Labeler App, but i am having challenges merging the annotations of multiple users together, because the path always changes, when we exchange our Datasets with newer annotations. Is there any way of merging two groundtruths + their regarding images from different computers?

Help is very much appreciated!

It looks like those functions are just regular copy/paste mechanisms, without the "intelligence" to change the path saved inside the .mat files which i am copying. Therefore no this doesn't help either.

I'd get the labeled image from user 2 and find the centroids. Then use pdist2() to find out which label number from image #1 is the closest to that from image #2. Then use that information to relabel the labeled image from image #2.
