How to show several images in the same figue - Matlab

Question

EDITTED:

Hii, sorry not mentioning it earlier, what I need to do is to display 6 images in the same figure at the same time. Besides, at every image (frame) I need to draw some points (my code tracks the moves of the face - the eyes, nose, lips.) I have 246 images (frames)

this is the main functions I use:

 // The points/ coordinates of the lips, eyes and nose of the image "i". Points = createPointsStructure (landmarks , i , NumOfLandarkPerFrame); // Draw landmarks and splines on the frame i (and draw/show the frame) DrawAllPointsOnFace (pointArr , Points , img , 1 , position, i);

Any ideas how can I do it?

I need to write a code that displays 6 images in the same figure (at the same time). and lets the user to choose one of the images to edit it (by clicking on it).

Any help how can I do it?

Thanks in advance.

Yes I have, but it didn't work as it should. Most of the figure was empty and the images were so small. — Howaida Khoureieh

@HowaidaKhoureieh: can you show the code you have tried so far? — Amro

For example:subplot(2,2,1),imshow(rand(50,50)) , subplot(2,2,2),imshow(rand(50,50)) , subplot(2,2,3),imshow(rand(50,50)) , subplot(2,2,4),imshow(rand(50,50)) — Chris

there is some gui programming here : mathworks.com/help/techdoc/creating_guis/… — Seçkin Savaşçı

Here is a simple example to get you started:

function ImagesExample() %# read images in a cell array imgs = cell(6,1); for i=1:6 imgs{i} = imread( sprintf('AT3_1m4_%02d.tif',i) ); end %# show them in subplots figure(1) for i=1:6 subplot(2,3,i); h = imshow(imgs{i}, 'InitialMag',100, 'Border','tight'); title(num2str(i)) set(h, 'ButtonDownFcn',{@callback,i}) end %# mouse-click callback function function callback(o,e,idx) %# show selected image in a new figure figure(2), imshow(imgs{idx}) title(num2str(idx)) end end

enter image description here

Another function to look into is the MONTAGE function from the IPT Toolbox:

%# given the above cell array `imgs` montage( cat(4,imgs{:}) )

@Amro, Thanks alot for the answer. It is really useful. But I editted the question, and would be very happy if you helped me with it. Thanks again.
