ImageDev

MaskImage

Masks a graylevel or color image I by a binary mask B.

Access to parameter description

The output image $O$ is given by the formula:
$$ O(n,m)=\left\{\begin{array}{ll} I(n,m) & ~\mbox{if $B(n,m) = 1$}\\ 0 & ~\mbox{if $B(n,m) = 0$}\end{array}\right. $$
Remarks: The same result can be obtained by See also
