how should i compress the some multiple images by 1st converting to them gray scale and all images are supposed to be of same size. here i tried to read 100s of images now i want to convert them to gray scale and then i supposed to compress them to make them of same dimensions...

myFolder = 'C:\Users\shree\Desktop\final data\1'; if ~isdir(myFolder) errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder); uiwait(warndlg(errorMessage)); return; end filePattern = fullfile(myFolder, '*.jpg'); jpegFiles = dir(filePattern); for k = 1:length(jpegFiles) baseFileName = jpegFiles(k).name; fullFileName = fullfile(myFolder, baseFileName); %fprintf(1, 'Now reading %s\n', fullFileName); imageArray = imread(fullFileName); imshow(imageArray); % Display image. drawnow; % Force display to update immediately. end

apologize me for any mistakes.... Regards,,,

This could be because you are using imshow.

Convert your image to grayscale using:

I = rgb2gray(img);

% Resize your image

I=imresize(I,[a,b]); specify the dimensions you want

% Finally write your image

% imwrite(I,'name.jpg');
