Connecting labelmatrix and regionprops Pixel indices

Hi all,

I have a list of 200-250 objects in a 512 x 512 image. I used bwconncomp to build a labelmatrix and also watershed and regionprops to measure the properties of the objects.

The properties table from regionprops provides each object's pixel indices in the 512 x 512 image.

How do I connect an object detected by regionprops/watershed with its corresponding label and location in the labelmatrix?

I am attaching examples of the labelmatrix and image files, as well as the output of regionprops.

Thanks a ton for your help!
