The most proper way to save images

Hello,

I am reading images and then applying some filters on them. In addition I want to save the output in a different folder. Yet the memory usage increases gradually.

here is the code I utilize:

for jj = 1:3000 % There are 3000 images.
    
    im = imread(fname);                 % 'fname' is defined for each image in above. it changes and it is preallocated at the beginning.
    im = im(20:770,70:820);             % Defining a proper frame size
 
    h = fspecial('gaussian',101,15);    % Filtering the image
    bim = imfilter(im,h,'replicate');   % Filtering the image
    bim = imfill(bim,'holes');          % Empty the center of the image 
    bim = imbinarize(bim);              % Turning the images into binary
        
    figure (jj);
    set(figure(jj), 'visible', 'off');
    imcontour (bim,1,'r');              % Drawing the contour of the image.
    axis square;

    folder = 'c:\PATH';
    ContourFileName = sprintf('Contour_for_image_no_%d',jj);
    fullContourName = fullfile(folder, ContourFileName);
    set(gcf,'Units','inches');
    screenposition = get(gcf,'Position');
    set(gcf,'PaperPosition',[0 0 screenposition(3:4)],...
        'PaperSize',screenposition(3:4));
    saveas(gcf,fullContourName,'tif');
    
end

I was wondering if there is another way to save the images without using a lot of memory. Because of the amount of images, after the 1000th images. it uses almost 95 percent of both memory RAM and CPU.

Thanks a lot for the help in advance and wish you a happy day filled with joy.

Do not use a different figure each time. Or delete the figure after you save the image.
