1   sec_path = [Save_path, Video_name, '/'];2   if ~exist (sec_path, ' file ') 3      mkdir ([Save_path, Video_name]); 4   End

2. Convert Gpuarray to a format that MATLAB can save, such as: Uint8.
  If you save the Gpuarray data directly, it'll warning you some errors like this:


and translate it into numeric or logical is necessary ...


      Single format using ' Gather ' function which is the MATLAB inside function.

im2uint8 (gather(person_image));
