Find nearest pixel to same for each pixel list given by regionprops for each object

Hello! I have a pixellist for each object given by regionprops and i want to calculate the nearest point and then distance all to the same binary map/object for each object.

Thanks!

If a pixel belongs to an object, its distance to the same object is zero, of course...

I agree with Matt. Please explain what you mean, preferably with a diagram showing the distances and blobs that you're talking about. Perhaps you mean the distance of every blob centroid to every other blob centroid like you'd get with pdist2()???
