假如要读取某个文件夹中所有的图片文件：clear all;
clc;
%%
slashtype = filesep;
%  FILESEP Directory separator for this platform.
%    F = FILESEP returns the file separator character for this platform.
%    The file separator is the character that separates
%    directory names in filenames.

options.dir = ['.',slashtype]; % The directory you would like to read

imext = {'.jpg','.bmp','.png','.tiff','.tif'}; % All the file extentions

% Read all the files in this directory with the extensions
[fileinfo,filenumber] = Read_Dir_Files(options.dir,imext);

Read_Dir_Files 函数如下：

function [fileinfo,filenumber] = Read_Dir_Files(inputdir,extention)
% This function read the files with all the input extensions in the directory 'inputdir'
% Input: inputdir  --- the directory you would like to go through
%       extention --- cells, have the extension you specified
% Output: fileinfo --- cells, fileinfo{i}.fullname fileinfo{i}.name
%                   fileinfo{i}.extension
%       filenumber -- the total number of files
%
% Example usage: [fileinfo,filenumber] = Read_Dir_Files('./',{'.m'})
%

files = dir(inputdir);  % get all the name of files and dirs under the folder 'inputdir'
% Here files can be file or a directory

%Loop over all filenames
ii=0;
for iF = 1:length(files)
%
if (~files(iF).isdir)
      %
      % If name is not a directory get detailed information
      %
      [pathstr, name, ext] = fileparts(files(iF).name);
      %    [PATHSTR,NAME,EXT,VERSN] = FILEPARTS(FILE) returns the path,
      %    filename, extension and version for the specified file.
      %    FILEPARTS is platform dependent.

      %Loop for all the extension
      for ie=1:length(extention)
         %
         % Compare to known extentions and add to list
         %
         if (strcmpi(extention{ie},ext))
            ii = ii + 1;
            ext = ext(2:end);
            fileinfo{ii}.fullname = [inputdir,name,'.',ext];
            fileinfo{ii}.name    = name;
            fileinfo{ii}.extension  = ext;
         end
         %
      end
      %
end
%
end
filenumber = ii;
if filenumber==0
fileinfo={};
end

end
