how to create stack with multiple images?
显示 更早的评论
Hi all,
I have a series of images and I want to make stacks of the images. The dimension of the stack should be like 2490*2490*7.
Here is the code I worte.
b=cell(7,9);
I_max=cell(7,9);
I_stack_store=cell(9,1);
I_stack=zeros(2975,2975,7);
for t=1:9
for i=1:7
I=imread(['calibrate2-P01.00' num2str(t) '00' num2str(i) '.tif']);
b{i,t}=I;
I_max{i,t}=max(b{i,t},[],3);
I_stack(:,:,7)=I_max{:,t};
I_stack_store{t}=I_stack;
end
end
I_max is a 7x9 array with each cell one image. (e.g. 2490*2490)
I want to get every column (7 images) of I_max into a stack, resulting 9 stacks which can be stored into a new array.
There must be something wrong with my code because I did not have the image l want.
Can someone help?
Thanks a lot!

b=cell(7,9);
I_max=cell(7,9);
I_stack_store=cell(9,1);
for t=1:9
for i=1:7
I= rand(50,10,3);
b{i,t}=I;
I_max{i,t}=max(b{i,t},[],3);
I_stack(:,:,i)=I_max{i,t}; % I_stack(:,:,7) if you only want the 7th col
end
I_stack_store{t}=I_stack;
end
I_stack_store

Assign the inner for loop index to
I_stack(:,:,i)=I_max{i,t}; % use i for loop index to store max values
I_stack_store{t}=I_stack; %

Yes, the code seems to do what you described. You can see the stack of 9 images as the output. However, there is one difference, please note this line
I_stack_store{t}=I_stack;
needs to be in outer for loop. This will essentially get all the correct images into one stack, which is 9 x 1 as seen from output. But If you use
I_stack(:,:,7)=I_max{:,t};
it will only store the last image ignoring other images.

The code I shown will do what you want. Please see the output I shown.
