How detect circle like objects from binary image
显示 更早的评论
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)
