As an estimator, we choose the center of mass of the observation: def ν = p(jâν) jâν (15) j where p(jâν) is the probability that the contour is between locations (jâ1/2)âν and (j + 1/2)âν on the normal under consideration. 9 1.3 Using OpenCV with Eclipse (plugin CDT) . 8 1.2 Using OpenCV with gcc and CMake .
