3 次查看(过去 30 天)
Hello there, I am trying to read jpg files from folder with a series of A1,A2,....A22 but when i read them with the following code they read A1,A10,A11,A12...etc then A2,A20,A21 .. etc alphabetically! how i can read them in my specific order?
myFolder = 'C:\Users\JUST\Downloads\Sana3';
% Check to make sure that folder actually exists. Warn user if it doesn't.
if ~isdir(myFolder)
errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
uiwait(warndlg(errorMessage));
return;
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.jpg'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile(myFolder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
% Now do whatever you want with this file name,
% such as reading it in as an image array with imread()
imageArray = imread(fullFileName);
%imshow(imageArray); % Display image.
f=(imageArray);
end

I'm virtually positive there's a sort routine on FEX for you...I forget whose submittal it was; I think maybe John D'Errico but won't swear it.
It illustrates why when you create such sequential names, alway use a naming pattern that will sort numerically as well as lexically -- like
>> num2str([1:3:22].','File%03d.jpg')
ans =
8×11 char array
'File001.jpg'
'File004.jpg'
'File007.jpg'
'File010.jpg'
'File013.jpg'
'File016.jpg'
'File019.jpg'
'File022.jpg'
>>
for example, and you wouldn't be having the problem.
