Images=dir('C:\Complete_path\hand_2101\*.png');
%.............................^^ Folder Name, where Images are there, note on png/jpg
outDirectory='C:\Complete_path\result_images\';
%.............................^^ Folder Name, where you wish to save the image
% Result images will save in the folder ^^result_images
%The result_images folder will cretes by following statement
mkdir(outDirectory);
for i=1:length(Images)
ImgName=strcat('C:\Complete_path\hand_2101\',Images(i).name);
grayImage=((imread(ImgName)));
% do operation, say result image is result1
result1=.....
imwrite(result1,strcat(outDirectory,Images(i).name));
end
