CombineByMask

Produces a combination of two images in a complementary way.

Access to parameter description

CombineByMask produces an output image $O$ which is the combination of two images $I_1$ and $I_2$ by following a binary mask B as follows:
$$ O(n,m)=\left\{\begin{array}{ll} I_1(n,m) & ~\mbox{if $B(n,m) = 1$}\\ I_2(n,m) & ~\mbox{if $B(n,m) = 0$}\end{array}\right. $$ See also
