Combine multiple Image Labeler datasets

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!

Merging them? Can't just copy the file and put them in the same path? 'Yes to all' if window notify there is a same name folder in the path.

No this doesn't work, because the Labels are named Label_x, and are not uniquely identifiable.

Will this help you?

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.
