Thanks for yours answers.

How can I save all the images this image directory on a two-dimensional array as input to train neural networks?

[Matt Fig]

I = dir('*.jpg');  % or jpeg or whatever.

for ii = 1:length(I)
   C{ii} = imread(I(ii).name);  % Store in a cell array.
end

Now the first image is stored as C{1}, the second as C{2}, etc...

My images were taken on a binary image with 0 is black bar, 1 is the white bars, after I read all images in this directory, pleaase help me how to save all the images were read on a vector-specific for barcode image to input training artificial neural network

this is my code:

myFolder = 'Tapmau';

filePattern = fullfile(myFolder, '*.bmp');

bmpFiles = dir(filePattern);

for k = 1:length(bmpFiles)

baseFileName = bmpFiles(k).name;

fullFileName = fullfile(myFolder, baseFileName);

% fprintf(1, 'Now reading %s\n', fullFileName);

imageArray = imread(fullFileName);

% imshow(imageArray); % Display image.

% drawnow;

% Force display to update immediately.

end

for i=1:length(bmpFiles)

baseFileName=bmpFiles(i).name;

fullFileName = fullfile(myFolder, baseFileName);

image=reshape(imageArray,[],1)

end

targets=eye(44);

can you fix it for me

Hope your help. Thanks so much
