Currently the only way to propagate changes to the classifier is to   write to a file, then reload the classifier in each thread from the file path. It would be nice if there was a cv::CascadeClassifier::clone() method for deep copying.\n```\n\nHistory\n-------\n##### Anna Kogan on 2012-12-06 07:10\n```\n-   Target version set to 3.0\n-   Assignee set to Maria Dimashova\n-   Category set to ml\n```\n##### Anna Kogan on 2012-12-06 10:45\n```\n-   Assignee changed from Maria Dimashova to Marina Kolpakova\n```\n##### Marina Kolpakova on 2012-12-06 10:46\n```\n-   Category changed from ml to objdetect\n```\n##### Marina Kolpakova on 2013-04-05 23:28\n```\n-   Assignee deleted (Marina Kolpakova)\n```"}}
