How to perform algebraic operations on an hyper stack image?
显示 更早的评论
I have sets of images in folders A,B, ... containing images of dimension (n x m).
How do I group the images and then perform one operation to get outputs A',B',.. where A' = (A-X)/X [X is another image of dimensions (n x m)]

Hi,
Below mentioned code takes all the files from a folder and save it to a matrix for matrix opeartion.
%chanage directory to the folder of your interest
cd /path_to_folder_of_interest
%lists all files/folders in the diretory
x = dir;
%iteerate over all files/folders inside a folder
for idx = 1:numel(x)
element = x(idx);
%checks if its not a directoey it will read from excel file and make it
%a matric for operation
if(~element.isdir)
if(exist("A","var"))
A = [A;table2array(readtable(element.name))];
else
A = table2array(readtable(element.name));
end
end
end
A1 = (A-X)/X;
It assumes all the file are excel files in the folder.
