overlapping and coloring pictures in a sequence

I have thi code to colorize pictures in folders and overlapping every two pictures to gether, but I manually change the name of each two files to overlap and also change the name of the written file. Is there is a code could help me to change the name automatically as I have about 1000 files in each folder. this is my code.

if true
a=imread('square 27_filter 4.tif');
b=imread('square 27_filter 5.tif');
% C = imfuse(a,b,'blend','Scaling','joint');
% imwrite(C,'Square_1.png'); 
% figure;imshow(a)
% figure;imshow(b)
% figure;imshow(C);
blackImage = zeros(size(a), 'uint8');
a_green = cat(3, blackImage, a, blackImage);
%blackImage = zeros(size(b), 'uint8');
b_red = cat(3, b, blackImage, blackImage);
%C_rg = imfuse(a_green,b_red,'blend','Scaling','joint');
imwrite(C_rg,'Square_27_Cycle_1.tif');
end

Hi,

If the name of the images you are trying to read differs only in some number in the name, for example name of images are square 27_filter 1, square 27_filter 2 etc, then you can use a sprintf command in a "for" loop to read the images without manually changing the names.

for i=1:n
  name = sprintf('square 27_filter %d.tif', i);
  a=imread(name)
  blackImage = zeros(size(a), 'uint8');
  % rest of your code
end

Hope this helps.

Thanks
