Hi, how can send a http command to ip camera ? i am going to send a command to camera after appear an event whit this command the camera go to preset. "http://160.10.52.100/rcp.xml?command=0x09A5&type=P_OCTET&direction=W RITE&num=1&payload=0x80000201B0800704XX".

before i capture video with this "VideoCapture capture("rtsp://username:[email protected]/?h26x=0");" i use visual studio c++.

thanks.

thanks a lot .. every thing is ok, i saw other error Of course, I did not need to these modules: 1_LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_dnn320d.lib'

2_LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_ximgproc320d.lib'

3_LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_tracking320d.lib'

4_>......\modules\ximgproc\src\fast_line_detector.cpp(185): error C3861: 'round': identifier not found

thanks

i rerun cmake and saw when build , this error appear "modules\xfeatures2d\src\boostdesc.cpp(244): error C3861: 'round': identifier not found" how solved it

in debug mode.

ok i do not have opencv_xfeatures2d320.lib in build . which module in opencv_contrib is for "xfeatures2d.lib"

if i only remove SURF process from my code , the compiler does not take error. then version of visual studio is ok. for example i detect background too .

i used this command but the compiler take error.

Hi, the error is: error LNK2019: unresolved external symbol "public: static struct cv::Ptr<class cv::xfeatures2d::surf=""> __cdecl cv::xfeatures2d::SURF::create(double,int,int,bool,bool)" (?create@SURF@xfeatures2d@cv@@SA?AU?$Ptr@VSURF@xfeatures2d@cv@@@3@NHH_N0@Z) referenced in function "void __cdecl campring(class cv::Mat const &,class cv::Mat const &)" (?campring@@YAXABVMat@cv@@0@Z)

Hi, i build opencv 3.2 with opencv-contrib moduls also add [ #include "opencv2/xfeatures2d.hpp"] and [using namespace cv::xfeatures2d;] to my code but i have error when compile it. i used these commands for surf:

    Ptr<SURF> detector; 
detector->create();
     detector->detect( imgbackground, Keypoints1 );

please guide me. thanks,

Hello,

does it possible to use c++ on Android (ONLY C++ AND ANDROID COMPONNET + OPENCV)?

(LIKE VISUAL STUDIO AND VC++ and opencv)

we do not want to use the java or JNI .

Thanks.

Hi, I am working with a video sender. That can communicate with it by the SDK(Software Development Kit). Every time a frame is ready then run an internal event below (the name is video-available) ,that we can do our processing in this event.

EVENT IS :
             video-available:
                                    {
                                       ENCODE-VIDEO_EVENT*   videoEventa;
                                     videoEvent = (ENCODE-VIDEO_EVENT*)     pData;

                                    server->process_jpeg_image(videoEventa->buff, videoEventa->size);

                                     break;
                                      }

we know frame will be send with ENCODE-VIDEO_EVENT* pointer.and the data structure is:

typedef struct { char* buff; int size; }

how can merge the video data to matrix? Many Thanks.

Yes, I can, but the background will change with time.

Hi, i want to calculate traffic jam. To do this I got the contours of the foreground.. But I have a big problem. If the traffic for a long time.And the cars do not move for several minutes.

As a result, the cars will be part of the background(the cars fade).

How can I solve this problem. Many Thanks.

Hi,

i detected the blobs with the SimpleBlobDetector class . how can i draw these blobs or extract to matrix?

How do I calculate the number of pixels inside the blob? and How can I determine its coordinates on the main image? Many Thanks.

Hi, berak i received the video stream . BUT i want to send a command via rtsp://............. i do not know this

Hi, i capture the video from the camera [VideoCapture capture=("rtsp://192.10.10.10/?h26x=0")] this is receive command.

how can i send a command with rtsp protocol to the camera ? for example ["rtsp: //192.10.10.10/?pre=0"] Many thanks.

Hi,

i create the .xml file with train cascade algorithm. with command ""detectMultiScale"" , i find the object but this object has large offset . how can i reduce the offset in the around object?

before training ,i selected ,,fit to object.

Many Thanks,

Hi, What is the best algorithm to determine the speed of the vehicle? 10 to 200 km/h. My camera support 60 frame per second.

Many Thanks

Hi, 1-can i train cascde algorithm with image color?Objects are the same, just a different color. 2- if i create the .xml file by MATLAB for cascade training . can i use the .xml file in opencv ?.is it compatible? Many Thanks.

Hi, What is the best algorithm to determine the speed of the car? Top 200 km. My camera support 60 frame per second. Many Thanks.

Very helpful.Thanks

haarcascade_frontalface_alt.xml and haarcascade_frontalface_default.xml and .. are not robust to rotate More than 10 degrees.

also which algorithm can back face to normal angle for face recognize process?

we have only 1 examples of each face. may create multiple copies of a photo Which are different in terms of brightness and angle,(3D Morphabe) , for use fisherface algorithm.

to implement fisher and eigenface algoritm need to have more than 2 sample for one image in database. Which algorithm is suitable for a sample؟

have lib files and bin folder. .So once must be build.

may be create dll files in bin folder for windows (opencv 3.0 rc1)
