How to copy 30K images from folder to another according to the names in train and test text listes

2 visualizaciones (últimos 30 días)
path = addpath(genpath('D:\DOCTORAT 2019\MATLAB Codes\datasets\NUS-WIDE-OBJECT\image list'));
DIR = 'D:\Dataset\NUSWIDE-Obj\imagesnus30k';%Source file
D_dir = 'D:\Dataset\NUSWIDE-Obj\Images30K';%Destination file (Sould be 31-subfolder=Nbre of classes)
class = {'bear','birds','boats','book','cars','cat','computer','coral','cow','dog','elk','fish','flags','flowers','fox','horses','leaf','plane','rocks','sand','sign','statue','sun','tiger','tower','toy','train','tree','vehicle','whales','zebra'}; %31 classes
tr = textread('Train.txt','%s');
ts = textread('Test.txt','%s');
imgs = vertcat(tr,ts);
for i =1:size(imgs,1)
% img = imread([ DIR,'\\',string(imgs(i,1))]);
imgname = (strcat(DIR, '\',string(imgs(i,1))));
img_files{i} = char(imgname);
fullFileName = fullfile(DIR, imgname);
% figure(1),imshow(img);
% imds = imageDatastore(img_files{i});
% img = readimage(imds,I);
% [img,info] = readimage(imds,2);

Sorry, i have corrected the question.
The code is juste to have a visual description of the subfolders (classes).

What is a "visual description" and a "class"?

With some guessing:
source = 'D:\Dataset\NUSWIDE-Obj\imagesnus30k';
dest = 'D:\Dataset\NUSWIDE-Obj\Images30K';
tr = textread('Train.txt', '%s');
ts = textread('Test.txt', '%s');
list = [tr; ts];
for k = 1:numel(list)
name = list{k};
copyfile(fullfile(source, name), fullfile(dest, name));

@riad didou: It would be much easier to post a working answer, if you provide a small set of input data. It is hard to guess, how the subfolder name has to be obtained, if you do not explain, what the inputs of your function is.
With some bold guessing:
for k = 1:numel(list)
name = list{k};
subfolder = fileparts(name);
src = fullfile(source, name);
destfolder = fullfile(dest, subfolder);
if ~isfolder(destfolder)
copyfile(src, fullfile(dest, name));
catch ME
if ~isfile(src)
error('File name not existing: %s', src)

Use copyfile to copy a file to a new location. You could probably use arrayfun to more quickly add the full file path to the file names output from the dir function. Or, you could probably pass a function to arrayfun that does the full file path creation and the copyfile all in one.

I dindn't understand; could you give me an example to illustrate how it works

You can type "doc copyfile" and "doc arrayfun" in MATLAB to bring up the documentation and examples of using both functions.
