[m, n] = size(crop); [q,z] = size(crop); i = 1 ;%column j = 1 ; %row %figure(1),imshow(crop); hold on; s = 0 ; while(j<m) while(i<n) rectangle('position',[i j 60 115] , 'LineWidth',1,'EdgeColor','red'); i= i+70; %45 i= i+1; s=s+1; ccc = imcrop(crop , [i j 60 115 ]); end baseFileName = sprintf('%d.bmp',i,j); fullName = fullfile( 'C:\Users\Isr\Documents\Matlab\pwd',baseFileName); imwrite(ccc, fullName);

       j= j+120; %58
       i= 1 ;
       j= j+1 ;

    end
