watershed results no stable in real time

Hi, I would like use watershed to segment objet in real time, in major case the segmentation work good on easy objet.

My problem is sometime watershed is not stable with 2 images interval where image almost the same and there are no major change. In next image we can see problem segmentation results(circle red is label 2, image contour label 1 and other label 0):

I try different filter step but results is worst.
