imdisp is a File Exchange contribution which has been replaced by SC

Anyhow: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Be careful if your images are named something img_9.bmp img_10.bmp and so on instead of img_09.bmp img_10.bmp (with fixed number of digits). If you use variable number of digits you will probably want to use https://www.mathworks.com/examples/matlab/community/19425-natsortfiles-examples

在 MATLAB Online 中打开

sorry some lines were missing in the above code:

dir_in = 'C:\Program Files\hemaMATLAB\R2007b\work\capinput\';
  dir_out = 'C:\Program Files\hemaMATLAB\R2007b\work\output\';
  file_ext = 'jpg';
listing = dir(strcat(dir_in,'i*.',file_ext));
numfile = length(listing);
>> image_stack = [];
>> for k = 1 : numfile
thisfile = listing(k).name;
thisimage = imread(thisfile);
image_stack(1:size(thisimage,1), 1:size(thisimage,2), :, k) = thisimage;
end
??? Error using ==> imread at 315
File "i1.jpg" does not exist.
