Center of mass

This operation is used to identify the Hough peaks in the peaks map (BinMap). It was proposed by Krieger Lassen (1998). [KriegerLassen1998] The center of mass is calculated using the intensity of the pixels as follow:

\[\left<\left(\theta, \rho\right)\right> = \left(\frac{\sum\limits_i^N{\theta_iI_i}} {\sum\limits_i^N{I_i}}, \frac{\sum\limits_i^N{\rho_iI_i}} {\sum\limits_i^N{I_i}}\right)\]

Its intensity is taken as the value of the closest pixel to the center of mass.
