Image sequence (images behind each other) MATLAB

Hi,

I want to create an image sequence with multiply images. I want to display my images behind each other, like in the following picutre:

I found this site: Work with Image Sequences as Multidimensional Arrays - MATLAB & Simulink - MathWorks Deutschland

And the commands cat, montage but I think with these commands I get an image sequence with images side by side.

My issue:

I have a matrix which I want to seperate in 10 matrices with same dimensions and display them an image sequence serially like I mentioned.

This is how I started. I think with the following command I can seperate my matrix in 10 matrices (scan).

scan=reshape(double(matrix), 20,100,10);

If I want for example display my third matrix I enter:

scan3=scan(:,:,3);

Now I dont know how to continue.

I was thinking about a for loop but I dont really know how to realize that.

I searched in the forum for similar questions but I did not find a similar question.

I hope my question is understandable.

Thank you

I am not sure if there is any MATLAB tool/function that does this specifically. But as a workaround, a simple script can create similar results. Try the following:

img1 = imread('AT3_1m4_01.tif');
img2 = imread('AT3_1m4_02.tif');
img3 = imread('AT3_1m4_03.tif');
img4 = imread('AT3_1m4_04.tif');
multi = cat(3,img1,img2,img3,img4);

I = img1;
pad = 0.1;
[ri, ci] = size(I);

for x=1:size(multi,3)-1
    [r, c] = size(I); 
    inew = uint8(zeros(floor([r, c]*pad) + [r, c]) + 255);
    inew(1:r, floor(c*pad)+1:end) = I;
    inew(end-ri+1:end, 1:ci) = multi(:,:,x);
    I = inew;
end

imshow(I);

Hey Tarunbir,

thank you for the code. I dont know if it fullfill my issue.

I have multiply images that I would like to open in one figure and switch image to image like a slide.

I just want to have my image in one figure and scroll in this figure to swtich to the next image.

I have therefore a big matrix which I seperatet in 10 smaller matrices. And these 10 matrices I want to display in one figure.

I hope it is more understandable.

Thanks.

Hi @Tarunbir Gambhir,

I show you what I tried without success.

For

scan=reshape(double(matrix), 20,100,10);

I tried

imshow(scan(;,;,;,1:end))

But I get this error

The use of imshow is incorrect here. You cannot achieve a slide-like image switcher using imshow. For the input, this function only takes a grayscale, or binary image as a 2-D matrix, or an RGB image of the format MxNx3. Please refer the documentation on how to use the function.

I can suggest you to try creating an app with a slider image view based on your requirements, using the App Designer.
