factMethMaskInc

Increase the mask of the Factorization Method.

function res = factMethMaskInc(seti,indx)
indx = seti.G(indx);
% Increase the mask
indxNew = indx;
n = max(1,round(seti.facMaskPer/100*seti.nROI)); % number of neighbor pixels
np1 = n+1;
for i = np1:size(indx,1)-np1 % (n+1):N-(n+1) instead of 1:N because we subtract or add n
    for j = np1:size(indx,2)-np1
        if indx(i,j) == 1
            indxNew(i-n:i+n,j-n:j+n) = 1;
        end
    end
end
indx = indxNew;
iG = @(x) x(:);
res = logical(iG(indx)); % mask of the obstacle
end
