Hello! I read images using imread, remove the lens distortion and then write it to a new created folder.The code works but I don't have the original name of the images anymore. I want that the image name e.g. 20160406.png is the same for the new undistorted image. How can I do that?

This is my code:

z=dir('*.png');
NewFolder=mkdir('NewFolder');
for k = 1:numel(z)
 X=imread(z(k).name);
 Y=undistortImage(X,cameraParams);
 imwrite(Y,['NewFolder/', num2str(k),'.png']);  
end

Try this:

files = dir('*.png');
if exist('NewFolder', 'dir')
    NewFolder=mkdir('NewFolder');
end
for k = 1:numel(z)
   % Get input base file name.
   thisImage = imread(files(k).name);
   % Correct the image.
   correctedImage = undistortImage(thisImage, cameraParams);
   % Create the output filename.
   baseFileName = files(k).name; % Same as source filename.
   fullOutputFileName = fullfile(NewFolder, baseFileName);
   % Save the output image.
   imwrite(correctedImage, fullOutputFileName);  
end
