counting number of white objects in BW image

I have an image, (see the attachment)

I want to count those white objects. I tried eroding and then tried to convert it to circular shaped looking objects (in order to count the number of circles)but after erosion, they don't actually convert exactly to a circular shape.

Is there any other simple way to count those objects?

Use this commands where Num is the number of white objects in the image.

    BW=your_binary_image;

    [L,Num] = bwlabel(BW);

HI, I just tried testinf this method on the provided image, and I am getting Num=27. Should it not be 25? Where am I going wrong?
