i work on Blood cell image to detect and count Red Blood Cell i use CircularHough_Grd Function to detecting circles i want to count circles which detected from CircularHough_Grd

i think to make for loop and save the detected elements in it and count but i can't do this. my image after detection : http://detectionrbc.blogspot.com/

this code which draw circles on detected objects in image : i want to count this circles which draw????

hold on;
plot(circen(:,1), circen(:,2), 'r+');
for ii = 1 : size(circen, 1)
   rectangle('Position',[circen(ii,1) - cirrad(ii), circen(ii,2) - cirrad(ii),  
   2*cirrad(ii), 2*cirrad(ii)],'Curvature', [1,1], 'edgecolor', 'b', 'linewidth', 1.5);
  end
  hold off;

Exactly what does "save the detected elements in it" mean? Do you want to save the image with the overlays, like you can with export_fig()? Or do you want to save the variables to a text file with fprintf() or a mat file with save()? Please clarify.
