How detect circle like objects from binary image

I want to detect number of objects from a binary image. As you can see below these objects are overlapped a bit with other objects. My objects are circle like objects (not excact circle).

Any help would be much appriciated.

You can measure the area or the approximate number of pixels that one of the circles occupies, then you take the area of ​​the total number of figures and divide it by the area that an object occupies.

im = imread('image.png');
u = graythresh(im);
im2 = im2bw(im,u);
circ_1 = 900; % aprox area of one circle
area_image=bwarea(im2); %area of all circles

N_circles = floor(area_image/circ_1)

Thakn you Diego Samaniego for your answer.

This a good idea to find the number based on a single circle's area. but the thing is I can not assume area of a circle because the ultimate goal is to find number of circles with it's diameter. Each circles may or maynot be same. And the system should find out this automatically.

I really appricate your answer. Do you have any sugestion for my situation?

Many thanks
