ifsize(im, 3)==1 % Gray-level image
img=zeros(sz(1),sz(2));
j=1;
imagesc(im); axis off; hold on; colormap gray;
fori=0:k_max-1
LL=(L_global_min==i);
is_zero=sum(sum(LL));
if is_zero
img(:,:,1)=img(:,:,1)+LL*c(j,1);
j=j+1;
end
if i~=i_ground
color=[rand rand rand];
contour(LL,[1 1],'LineWidth',2.5,'Color',color); hold on;
end
end
figure(2);
imagesc(img); axis off;

imagesc() applies it's own crazy idea of how it thinks you want the image pseudocolored, and it's almost always wrong. I suggest you don't use it -- I never do. Use imshow() instead. If you want a colormap, pick one of your own choosing with the colormap() function.
