2013-02-02 01:52:02 -0600 | asked a question | AdaBoost with SVM as weak learner hi. i want to know if there are any implementation of adaboost that uses an svm as a weak classifier ? i want to use it in cascade classifier to detect faces faster. |

2012-12-14 23:56:58 -0600 | asked a question | multi threading cascadeclasifier hi. the cascadeclassifier is multithreaded with tbb but when i don't build opencv with tbb it still working concurrently and get more than 25% of cpu ( more than one core). how can i disable multithreding of cascadeclassifire ?! |

2012-11-30 22:24:05 -0600 | commented answer | cascadeclassifier value not yet !, becuse i dont want to use those individually. i want to use only CascadeClassifier::detectmultiscale() and to build my project. |
2012-11-28 07:17:42 -0600 | commented answer | cascadeclassifier value cascadeclassifire has two detectmultiscale functions that one of them calls another one. the main function is : void CascadeClassifier::detectMultiScale( const Mat& image, vector<Rect>& objects, vector<int>& rejectLevels, vector<double>& levelWeights, double scaleFactor, int minNeighbors, int flags, Size minObjectSize, Size maxObjectSize, bool outputRejectLevels ) we can use levelweight to compute probability of true detection. :) |

how can i get a value from detectmultiscale function that expresses a probability of true detection ?. |
2012-11-19 00:09:20 -0600 | asked a question | latentSVM vs CascadeClassifier hi, I want to compare LatentSVM and CascadeClassifire in the term of accuracy and speed. Which one is faster and which one is more accurate for an object detection task. thanks |

2012-11-18 23:08:16 -0600 | commented answer | multithreaded cascade classifire thakns, I found following sentence under documentation of CascadeClassifier::detectMultiScale, that is : The function is parallelized with the TBB library. http://docs.opencv.org/modules/objdetect/doc/cascade_classification.html#cascadeclassifier-detectmultiscale |
2012-11-18 22:10:27 -0600 | commented answer | multithreaded cascade classifire I know traincascade can works multithreaded, but i want use cascadeclassifier mutithreaded. I want multi threading in detection stage not in learning stage ! |
2012-11-18 07:08:40 -0600 | asked a question | latentsvm xml file hi How can i build my own xml file for latentsvm detector to detect my own model in an movie or camera ? I want to know if there is any program like traincascade.exe to train my latentsvm detector ? thanks |
2012-11-18 07:00:22 -0600 | asked a question | multithreaded cascade classifire hi i want to know whether or not the cascadeclassifire can detect multithread ? and if yes, how can i enable multithreading in cascadeclassifire. I use detectmultiscale() function but i think it is not multithread. I want to use it in an realtime software and want to use it in multithreaded way. thanks |
