Align & Distribute Multiple images in An image

I need to Align & Distribute multiple small images evenly in a big image. Just need "positioning", don't need to rotate or skew any image. More specifically, i need to distribute multiple SMALL images all on single Big image (which will be considered as Background image for all those small objects).

Found something extremely useful (here at https://www.mathworks.com/help/matlab/ref/align.html), but not sure (infact don't know) how to use it to distribute/align images,

Need Help, Thanks

Is it possible with matlab?

If I understood correctly you don't want to display multiple images in a single figure axis as in SUBPLOT or MONTAGE, instead you want to create a background image (Matrix) to fit all these small images into it as of your requirement.

Matlab doesn't have any built-in functions to do this, but you can write some hard written code to address this requirement.

I am writing some sample code which aligns five images with 3 and 2 images in each row respectively, you can modify it to fit your criteria.

% Five random images..
I1 = rand(100);
I2 = rand(20,50);
I3 = rand(80);
I4 = rand(60,20);
I5 = rand(120);

% size of each image..
[r1, c1] = size(I1);
[r2, c2] = size(I2);
[r3, c3] = size(I3);
[r4, c4] = size(I4);
[r5, c5] = size(I5);

% Now get the max Image size for the background..
% I am considering 3 images in first row and 2 images in second row..
% First Row cords
Rows1  = [r1, r2, r3];
Cols1 =   [c1, c2, c3];
maxRows1 = max(Rows1);
MaxRows1 = max(Rows1);
MaxCows1 = sum(Cols1);

% Second Row cords
Rows2  = [r4, r5];
Cols2 =   [c4, c5];
MaxRows2 = max(Rows2);
MaxCols2 = sum(Cols2);

% Max BackGround Size
BGRows = sum([MaxRows1,MaxRows2]) + 30; % 30 extra rows to leave uniform spaces..
BGCols = max(MaxCows1,MaxCols2) + 40; % 40 extra cols to leave uniform spaces..
% BackGroundImage 
BG_Image = zeros(BGRows, BGCols);

% Map these five images onto background..
% First Row
BG_Image(11:c1+10,11:r1+10) = I1;
BG_Image(11: r2+10 , c1+21:c1+c2+20 ) = I2;
BG_Image(11: r3+10 , c1+c2+31:c1+c2+ c3 +30 ) = I3;
% Second Row
BG_Image(maxRows1 + 21: maxRows1 + r4 + 20, 11:c4+10) = I4;
BG_Image(maxRows1 + 21: maxRows1 + r5 + 20, c4 + 21 :c4 + c5+ 20) = I5;
figure, imshow(BG_Image);

I don't know why you want to do this but good luck !!
