Mat result = img1 + img2;

imshow("h", result);

Mat re1 = result1 - img1;

imshow("h1", re1);

img1 and img2 are Binary image.

But image 're1' have other color, no only have White and Black

How to solve this problem???????

I think that the matrix 'result' and 're1' establish in the type of binary image matrix. But I don't know what to do.

I used 'bitwise_and(img1,img2,result)' Pero have other color, too.
