Hi all,
I have two folders with same number of same dimnesion images : one for the greyscale images and one for the RGB images. I'm looking for a way to use imfuse (or a function like that) to combine image 1 from one folder to image 1 from the second folder, then image 2 from one folder to image 2 from the second folder, image 3 to image 3 etc etc..
edit: I'm looking for an aoutomatic way to do this for all the 230 + 230 images.
I'm an archaeologist so not really expert with code, but I learn fast!!
Thnaks a lot for any help!

You can do pretty much anything you want in matlab. The amount of effort can of course vary. As long as you have a rule for matching images from one set to the images of the other it should be easy. If it's just matching them in numerical order then it's easy.

Yes! I need to match them in numerical order. Do you have some suggestions or maybe a code the suits for my needs?

Step 1: Download Stephen's natsortfiles.
Then adapt as needed. I still don't know what you want as output. I assume new images in another folder
folder1 = 'C:\somewhere\somefolder';
folder2 = 'C:\somewhere\someotherfolder';
folderout = 'C:\anothersomewhere\something';
outfilepattern = 'FancyName%03d.tif'; %see the documentation of sprintf for format string syntax
filelist1 = dir(fullfile(folder1, '*.tif'));
filelist2 = dir(fullfile(folder2, '*.tif'));
assert(numel(filelist1) == numel(filelist2), 'Mismatch between file count in input folders.');
filelist1 = natsortfiles({filelist1.name});
filelist2 = natsortfiles({filelist2.name});
for fidx = 1:numel(filelist1)
img1 = imread(fullfile(folder1, filelist1{fidx}));
img2 = imread(fullfile(folder2, filelist2{fidx}));
img_fuse = imfuse(img1, img2, 'montage'); %works even if one image is greyscale and the other is rgb. Smaller images get padded to fit the size of the larger one.
imwrite(img_fuse, fullfile(folderout, sprintf(outfilepattern, fidx)));

You can use the imfuse function to combine the images in the same plane. Have a look at the doc for more infos.
if you want to combine GRB and greyscale images, you might want to convert them both to RGB first:
rgbImage = cat(3, grayImage, grayImage, grayImage);
or if greyscale suffices:
rgbImage = ind2rgb(grayImage, colormap);

Yep, ok. But I need to combine 235 images from one folder to the 235 images of the other one: frist with first, second with second etc etc... I'm looking for an aoutomatic way to do this. Thx for any suggestion.

Note that imfuse will automatically convert a greyscale image to RGB if the other is RGB, no need to do this yourself.
