在 MATLAB Online 中打开

1) I am attaching a self explanatory code

% Get list of all jpg files in this directory
imagefiles = dir('*.jpg');      
nfiles = length(imagefiles);    % Number of files in the folder
for i=1:nfiles
   currentfilename = imagefiles(i).name;
   currentimage = imread(currentfilename);
   images{i} = currentimage;
end

2) Please refer to this documentation Here for selecting a rectangular region of Interest
