hi i have some paramettres in my principal programme this paramettres changed when i change the image i need to do a fonction and to extraire the paramettres from the principle paramettres to the fonction

lb=100%lower threshold(ignore CSF,air)
% %  nhood=ones([8 8 6]);

so ib=100 for im1 and ib=150 for next image i need to create a fonction
