Object B should be visible over object A where they overlap. I eddited the post to include the first part of the code. If you have a bunch of them, they will blend if touch each other. Afterwards, you can easily overlay the segmentation by doing: plt.imshow (Image2_mask, cmap='jet', alpha=0.5) # interpolation='none' Changing the alpha will change the opacity of the overlay. any nonzero pixels are considered to be. Now you are completely ready to laminate images with your segmentation.
