Batch-processing data files in a directory tree with Matlab

You may find the following code useful to process data with Matlab in a batch fashion. This example processes all the PNG files within the first level of directories that hang under the current directory, that additionaly have "noise" as a part of its name and "gif_" is not to be found within the name.

for i=1:N
    name=files(i).name;
    if (files(i).isdir == 0) && strcmp(name(end-3:end),'.png') && _

           isempty(strfind(name,'nois')) && _

           ~isempty(strfind(name,['gif_' num2str(s)]))

           im=double(imread(name)); 

           [your processing here]

    end
end
