Image Processing Toolbox, and the regionprops() function of it. It will probably not give a direct calculation of the circumference though.

regionprops gives you the major and minor axis lengths. You can use those to calculate the circumference of a circle or ellipse.

what about how to know the x,y position of each dots that build the circle or maybe rectangle??

regionprops() can return that information as well.
