Hello,
I have a list of 100 different pictures.
I have the name of the 100 pictures, for instance :
bananas
strawberrys
etc
I want to select those 100 images in the folder in which there are 200 images in total.
I can do this by hand, but does anyones have an idea of code to do so ?
Thanks a lot

Assuming you have the required image names in a text file. Refer the code below.
myFolder = 'putYourFolderPathHere';
filePattern = fullfile(myFolder, '*.tiff'); % Change the extension according to your file extension
tiffFiles = dir(filePattern);
fid = fopen('fileNameList.txt', 'rt'); % Assuming fileNameList.txt contains the names of the required images
idx = 1;
while feof(fid) == 0
tline = fgetl(fid);
fileNamesToBeInc{idx} = tline;
idx = idx+1;
end
for k = 1:length(tiffFiles)
baseFileName = tiffFiles(k).name;
for i = 1:length(fileNamesToBeInc)
if strcmp(fileNamesToBeInc{i}, baseFileName)
fullFileName = fullfile(myFolder, baseFileName);
temp{k} = imread(fullFileName);
end
end
end
imageArray = temp(~cellfun('isempty',temp)); % imageArray contains your image files
% Display all the selected images
montage(imageArray);

Yes, because your text file only contains the name of the images without their extension (e.g., .jpeg, .tiff, .png, etc.). Use the code below which appends the extension after the filenames.
myFolder = 'putYourFolderPathHere';
filePattern = fullfile(myFolder, '*.tiff'); % Change the '*.tiff' extension according to your file extension
tiffFiles = dir(filePattern);
fid = fopen('images_cent_names.txt', 'rt'); % Assuming fileNameList.txt contains the names of the required images
idx = 1;
while feof(fid) == 0
tline = fgetl(fid);
fileNamesToBeInc{idx} = tline;
idx = idx+1;
end
fclose(fid);
temp = cell(1, length(fileNamesToBeInc));
% Appending extension
for k = 1:length(fileNamesToBeInc)
fileNamesToBeInc{k} = [fileNamesToBeInc{k}, '.tiff']; % Change the '.tiff' extension also according to your file extension
end
% Reading files
idx = 1;
for k = 1:length(tiffFiles)
baseFileName = tiffFiles(k).name;
if ismember(baseFileName, fileNamesToBeInc)
fullFileName = fullfile(myFolder, baseFileName);
temp{idx} = imread(fullFileName);
idx = idx + 1;
end
end
imageArray = temp(~cellfun('isempty', temp)); % imageArray contains your image files
