サブフォルダから画像を読み込んで別のフォルダに保存

Question

ここにコードがあります。

start_path = fullfile(matlabroot, '\toolbox\images\imdemos'); 
% Ask user to confirm or change. 
topLevelFolder = uigetdir(start_path); 
if topLevelFolder == 0 
    return; 
end 
% Get list of all subfolders. 
allSubFolders = genpath(topLevelFolder); 
% Parse into a cell array. 
remain = allSubFolders; 
listOfFolderNames = {}; 
while true 
    [singleSubFolder, remain] = strtok(remain, ';'); 
    if isempty(singleSubFolder) 
     break; 
    end 
    listOfFolderNames = [listOfFolderNames singleSubFolder]; 
end 
numberOfFolders = length(listOfFolderNames) 

% Process all image files in those folders. 
for k = 1 : numberOfFolders 
    % Get this folder and print it out. 
    thisFolder = listOfFolderNames{k}; 
    fprintf('Processing folder %s\n', thisFolder); 

    % Get PNG files. 
    filePattern = sprintf('%s/*.png', thisFolder); 
    baseFileNames = dir(filePattern); 
    % Add on TIF files. 
    filePattern = sprintf('%s/*.tif', thisFolder); 
    baseFileNames = [baseFileNames; dir(filePattern)]; 
    % Add on JPG files. 
    filePattern = sprintf('%s/*.jpg', thisFolder); 
    baseFileNames = [baseFileNames; dir(filePattern)]; 
    numberOfImageFiles = length(baseFileNames); 
    % Now we have a list of all files in this folder. 

    if numberOfImageFiles >= 1 
     % Go through all those image files. 
     for f = 1 : numberOfImageFiles 
      fullFileName = fullfile(thisFolder, baseFileNames(f).name); 
    pathname = strcat('C:\\xampp\\htdocs\\PACS_Client\\cbir_matlab\\ano\\'); 
    outputBaseFileName = sprintf('%3.3d.jpg',f); 
    outputFullFileName = fullfile(pathname, outputBaseFileName); 

    fprintf('Processing image file %s\n', fullFileName); 
    im=imread(fullFileName); 
    imshow(im); 
    data = im; 
    imwrite(data,[pathname,outputBaseFileName]); 
     end 
    else 
     fprintf('  Folder %s has no image files in it.\n', thisFolder); 
    end 
end 

私は別のfolder.Butにサブフォルダからのすべての画像は、画像の全てimages.Onlyいくつかの数字を取得できませんでした保存しようとしたsaved.Iはすべてimages.can誰もが私を助けて保存したいですこのコード？

Answer 1

あなたのコードを少し更新しました。これがうまく動作するかどうか確認してください。あなたの基本ファイル名である1つの問題は常に '％3.3d.jpg'です。そうでない場合でもすべての画像は '.jpg'になります。また、イメージをロードして表示していますが、コピーする必要があるだけなので、copyfileに行くことができます。 3つ前のフォルダから最後の001.jpgを上書きするすべての画像001.jpgを常に設定します。次のフォルダが高い番号で始まるように番号を追加する必要があります。

start_path = fullfile(matlabroot, '\toolbox\images\imdemos'); 
% Ask user to confirm or change. 
topLevelFolder = uigetdir(start_path); 
if topLevelFolder == 0 
    return; 
end 
%dir where everything should go. if the destination is not the 
%topLevelFolder 
%destinationpath = strcat('D:\\pics\\'); 
destinationpath = topLevelFolder; 

% Get list of all subfolders. 
allSubFolders = genpath(topLevelFolder); 
% Parse into a cell array. 
remain = allSubFolders; 
listOfFolderNames = {}; 
%while true 
% [singleSubFolder, remain] = strtok(remain, ';'); 
% if isempty(singleSubFolder) 
%  break; 
% end 
% listOfFolderNames = [listOfFolderNames singleSubFolder]; 
%end 
%your while worked fine, but try to avoid 'while true' with break 
for i=1:sum(strfind(allSubFolders,';')) 
[singleSubFolder, remain] = strtok(remain, ';'); 
listOfFolderNames = [listOfFolderNames singleSubFolder]; 
end 
numberOfFolders = length(listOfFolderNames) 

%set inital count 
picturecount=0; 
% Process all image files in those folders. 
for k = 1 : numberOfFolders 
    % Get this folder and print it out. 
    thisFolder = listOfFolderNames{k}; 
    fprintf('Processing folder %s\n', thisFolder); 

    % Get PNG files. 
    filePattern = sprintf('%s/*.png', thisFolder); 
    baseFileNames = dir(filePattern); 
    % Add on TIF files. 
    filePattern = sprintf('%s/*.tif', thisFolder); 
    baseFileNames = [baseFileNames; dir(filePattern)]; 
    % Add on JPG files. 
    filePattern = sprintf('%s/*.jpg', thisFolder); 
    baseFileNames = [baseFileNames; dir(filePattern)]; 
    numberOfImageFiles = length(baseFileNames); 
    % Now we have a list of all files in this folder. 

    if numberOfImageFiles >= 1 
     % Go through all those image files. 
     for f = 1 : numberOfImageFiles 
       fullFileName = fullfile(thisFolder, baseFileNames(f).name); 
       [~,~,ext] = fileparts(baseFileNames(f).name); %get extension 
       outputBaseFileName = sprintf(['%3.3d' ext],f+picturecount);%create name based on picturecount 
       outputFullFileName = fullfile(destinationpath, outputBaseFileName); 

       %fprintf('Processing image file %s\n', fullFileName); 
       %im=imread(fullFileName); 
       %imshow(im); 
       %data = im; 
       %imwrite(data,[pathname,outputBaseFileName]); 
       %you dont need it in matlab just copy the file 
       copyfile(fullFileName,outputFullFileName); 
     end 
     picturecount=picturecount+numberOfImageFiles;%set picturecount for next k 
    else 
     fprintf('  Folder %s has no image files in it.\n', thisFolder); 
    end 
end 

Answer 2

問題はbaseFileNames = dir(filePattern)にあります。ループが新しいフォルダに追加されるたびにリストがリセットされます。このため、最終的には最後のフォルダの画像しか持たないのです。 forループの直前にbaseFileNames = []を追加して、baseFileNames = dir(filePattern)をbaseFileNames = [baseFileNames; dir(filePattern)]に置き換えます。
