Trace boundaries of objects in NOT binary images

Hello,
I'd need some help. I need to trace region boundaries in an image. I would need exactly what bwboundaries does but in multi-label images because my image is not binary.
I have a lot of objects, holes, objects inside other objects ... I have to detect all the objects and get its boundaries. I have found only bwboundaries but i couln't find anything for not binary images.
Thank you very much

You can binarize the image and then call it
binaryImage = labeledImage > 0
If the objects are touching and still labeled (which you must have done with a custom algorithm) then you will need multiple binary images:
binaryImage = labeledImage == labelNumberThatYouWant;
do it for every label number that you want the boundary of.

I have no idea what you want - no idea what "deal with" means to you. Start a new question and attach your image(s).
