MATLAB: Facing problem in saving the images in folder

crop imagesdetect facesave imges

I need some help in my code. I am trying to read the images from a folder and detect faces from then and save the cropped images in another folder. But while running the code it is not saving the cropped images into the folder properly. It's overwriting the images.

HER IS THE CODE

Folder = 'OUTPUT';
FileList = dir(fullfile(Folder, '*.jpg'));
for iFile = 1:numel(FileList)
File = fullfile(Folder, FileList(iFile).name);
I = imread(File);
% figure(1),imshow(I);
FaceDetect = vision.CascadeObjectDetector; 
BB = step(FaceDetect,I);
% figure(2),imshow(I);
for i = 1:size(BB,1)
rectangle('Position',BB(i,:),'LineWidth',3,'LineStyle','-','EdgeColor','r');
end
for i = 1:size(BB,1)
J= imcrop(I,BB(i,:));
M = imresize(J,[48 48]);
imgray=rgb2gray(M);
fname = sprintf('%06d.jpg',i);
fpath = fullfile('Fdetected', fname);
imwrite(imgray,fpath);
end
end

Best Answer

The 'fname' line of your code:

fname = sprintf('%06d.jpg', i);

should be in the outer most for loop. Then the 'i' will correspond to different input images. Presently, it seems to be another intermediate variable used for cropping the image.

MATLAB: I have few images, i want to create folders, and names of folders should be identical to images. and want to save those images in folders having identical names.

Try this:

% Specify the folder where the files live.
myFolder = 'D:\My Pictures\Misc'; % Wherever...
% 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, '*.PNG'); % 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.
  drawnow; % Force display to update immediately.
  % Create a folder with the base file name
  [~, baseFileNameNoExt, ~] = fileparts(baseFileName);
  outputFolder = fullfile(myFolder, baseFileNameNoExt);
  if ~exist(outputFolder, 'dir')
    mkdir(outputFolder);
    fprintf('Created folder : %s\n', outputFolder);
  end
  % Prepare output filename
  outputFileName = fullfile(outputFolder, baseFileName);
  % Copy file to that folder
  copyfile(fullFileName, outputFileName);
  fprintf('    Copied %s to the folder called %s.\n', baseFileName, outputFolder);
end

MATLAB: I have this code and I want to perform this process on multiple images. kindly help me through code.

[filename, filepath] = uigetfile ({'*.jpg';'*.bmp';'*.png'}, 'File Selector', ...
        'MultiSelect', 'on');
filename = cellstr(filename);
for iFile = 1:numel(filename)
  img = fullfile(filepath, filename{iFile});  % Better than STRCAT
  img = imread(img);
  figure    % New figure, do not specify the index
  imshow(img);
  FaceDetect = vision.CascadeObjectDetector;
  FaceDetect.MergeThreshold = 7 ;
  BB = step(FaceDetect,img); figure(2),imshow(img);
  for i = 1:size(BB,1)
     rectangle('Position',BB(i,:),'LineWidth',3,'LineStyle','- ','EdgeColor','r');
  end
  figure
  for i = 1:size(BB,1)
    J= imcrop(img,BB(i,:));
    subplot(6,6,i);
    imshow(J);
  end
end
