A = imread('image.png'); % image.png is the image posted, which is a logical array
A_out = zeros(size(A),'uint8'); % greyscale output image -> 2-D uint8
A_out(~A) = 229; % background = 229
A_out(A) = 22; % foreground = 22
% A_out is the requested output image
imwrite(A_out,'image_out.png'); % write it to file if you like
