Count elements on image

Hi all,

I had two problems when I used the next code for counting circles on the attached images (erodedBW is the image input)

 subplot(2, 2, 1);imshow(A);
 fontSize = 20;
 binaryImage = erodedBW(:,:,1) < 200;
 title('Original', 'FontSize', fontSize);
 subplot(2, 2, 2);imshow(A);
 title('Binary Image with Centroids', 'FontSize', fontSize);
 hold on;
 format longg;
 format compact;
 measurements = regionprops(erodedBW, 'Centroid', 'Area');
 numberOfCircles = length(measurements);
 allAreas = [measurements.Area]
 for k = 1 : numberOfCircles
  centroid = [measurements(k).Centroid];
  xCenter = centroid(1);
  yCenter = centroid(2);
  plot(xCenter, yCenter, 'b+');
 [counts values] = hist(allAreas);
 subplot(2, 2, 3);imshow(erodedBW);
 title('Eroded', 'FontSize', fontSize);
 message = sprintf('The number of circles is %d', numberOfCircles);
 msgbox(message);

The first problem is that the algorithm counts a circle in the center. And the other is that counts more than one circle on the same element.

I need detect two elements (the two blobs)

I need detect two blobs on the left.

Thanks
