It should detect all the vehicles, no? 2013-02-28 01:36:09 -0500 asked a question Random Vehicle Detection Hi all. I want to calculate the average speed of the vehicle that is crossing the camera. So for that I want to detect the time that is taken by Random vehicle to cross the camera. By using that I can calculate the speed. ( speed=distance/timetaken ). Which method should I use? Can I detect a single object randomly? 2013-02-26 09:04:00 -0500 received badge ● Editor (source) 2013-02-26 09:01:10 -0500 asked a question Comparing Images by getting Percentage in open cv Hi Guys..

I have a doubt that whether we can do face recognition using Haartraining. By taking the required number of positive and negative images.. And by marking The person that we want to be detected from the positive images.. Will it work? Any suggestions Please? 2013-02-12 02:16:07 -0500 asked a question Building haartraining files in open cv I need to create a .exe file from the training samples that come with open cv(Windows)..

I have created a text file that contains the object points that we focus on, using Object object marker utility. Now I need to compile createsample.cpp file to create .exe file, as I read it in tutorial. I really dont know how we can do that. Read somewhere that I need to make use of the CMakeListss add_executable(opencv_createsamples cvhaartraining.h createsamples.cpp) set_target_properties(opencv_createsamples PROPERTIES DEBUG_POSTFIX "\${OPENCV_DEBUG_POSTFIX}" OUTPUT_NAME "opencv_createsamples") Can anyone please tell me how I can do that?
