- Binarize the image so that it's logical. binaryImage = grayImage > 128
- Call binaryImage = imclearborder(binaryImage) to get rid of the single line around the perimeter.
- Invert the image: binaryImage = ~binaryImage, so now black circles are white
- Call binaryImage = imclearborder(binaryImage) to get rid of the large (now white) background
- Call bwlabel: [labeledImage, numberOfCircles] = bwlabel(binaryImage). This gives you the count.
- Call measurements = regionprops(labeledImage) if you want other measurements

It's just basic, elementary image segmentation via intensity thresholding. Nothing fancy at all. See updated instructions above.

You could use techniques shown in many MATLAB image processing demos.
