As you can see I have 2 binary images. I want to mask first image with second image. I want to eliminate regions or convert logic-0 in first image with using second image's logic-0 regions. How can I solve this problem? Thank you for your help.
Red marked regions are unwanted. And I want to remove these regions with using second image

couldn't you just NewImage = Mask1&Mask2? where the only things left are the areas where both masks have the value 1? imagesc(Mask1&Mask2),colormap gray
or are you looking for the 0 areas in mask2 in mask 1? then i would do above but invert the 0/1 logic in mask 2.
imagesc(Mask1&~Mask2),colormap gray
