 Your can specify ```flags``` to fix parameters during calibration. Use 'plus' operator to set multiple features. For example, ```CALIB_FIX_SKEW+CALIB_FIX_K1``` means fixing skew and K1.
 
-```critia``` is the stopping critia during optimization, set it to be, for example, cv::TermCriteria(cv::TermCriteria::COUNT + cv::TermCriteria::EPS, 200, 0.0001), which means using 200 iterations and stopping when relative change is smaller than 0.0001.
