How to show title and xlabel on the bottom of every image?

Hi

I'm trying to show images with subplot in uipanel with their name and ordinal number at the bottom of the images and I am using this code:

[I,cmap] = imread('bone-17.gif');

      for j=1:4
          ax=subplot(2,2,j);
          image(I);
          colormap(ax,cmap);
   axis off;
  axis image;
       title(img.name(j));
      xlabel(ordinal_number,'FontSize',7);
      end

but this displays only the title and on the top of images and xlabel isn't showen at all how can I display title and xlabel on the bottom of every image? Or is it possible with one function to do that,something like this in for loop

title(img.name(j),ordinal_number)

Thank you

Try using text. Alternatively, there's the slightly more user-friendly ntitle available on File Exchange, but ntitle only places title inside axes. Here we do both:

I = imread('coins.png');
for k=1:4
    ax=subplot(2,2,k);
    imagesc(I);
    colormap bone
    axis off;
    axis image;
    switch k 
        case {1,2} 
            ntitle(['title ',num2str(k)],...
                'location','north',...
                'backgroundcolor','w');
            ntitle(['xlabel ',num2str(k)],...
                'location','south',...
                'FontSize',7,...
                'backgroundcolor','y');
        otherwise
            text(.5,1,['title ',num2str(k)],...
                'horiz','center',...
                'vert','bottom',...
                'units','normalized')
            text(.5,0,['xlabel ',num2str(k)],...
                'horiz','center',...
                'vert','top',...
                'FontSize',7,...
                'units','normalized')
    end
end

A note: try not to use i or j as variables. It can occasionally cause problems because by default they equal the imaginary unit.

I downloded function ntitle and when I try to run program it has some error

Undefined function 'ntitle' for input arguments of type 'char'.

What should I type in ntitle instead of ...

[Chad Greene]

Did ntitle get left in your downloads folder, or somewhere Matlab can't find it?

I believe it's because you turned the axis off that the labels don't show up. Why not leave them on and just set all your tick mark labels to null?

[Lolipop]

yes..but then I have some numbers on x and y axes the only way to turn off that numbers is to turn off the axes

[Image Analyst]

Doesn't this do what you want:

filename = 'kids.tif';
[indexedImage,cmap] = imread(filename);

for k = 1 : 4
  ax=subplot(2,2,k);
  imshow(indexedImage);
  colormap(ax,cmap);
  title(filename, 'FontSize', titleFontSize);
%   axis off;
  axis image;
  ordinal_number = sprintf('Image #%d', k);
  xlabel(ordinal_number, 'FontSize', axisFontSize);
  ylabel('y-axis', 'FontSize', axisFontSize);
end
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);

[Lolipop]

Well yes it would work but from some reason my gif images which are black and white won't show..well some of them are showen but some of them are just showen as black picture and with

image

can be showen all

And my question was how to display title and xlabel on the bottom of every image,problem is when pictures are different sizes and sometimes title and xlabel are being hidden because picture is too big

seg = svm(ad, m, 50); %-- Run segmentation

subplot(2,2,4); imshow(seg); title('Segmented Tumor');
%imwrite(seg,'test.jpg');

it shows SVM classifier name on classified image

i want to hide that name ?

how is it possible ??
