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

2017-01-23 07:07:47 -0500 commented question sift and surf in opencv 3.2

in debug mode.

2017-01-23 06:59:48 -0500 commented answer sift and surf in opencv 3.2

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

2017-01-23 06:38:10 -0500 commented question sift and surf in opencv 3.2

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 .

2017-01-23 06:12:19 -0500 commented answer sift and surf in opencv 3.2

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,

2016-01-25 03:48:45 -0500 asked a question use c++ on android without java and jni

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.

2015-12-10 07:27:15 -0500 asked a question how can merge the video data to a matrix?

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.

2015-09-23 13:09:19 -0500 asked a question cars fading in traffic jam

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, 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.

Very helpful.Thanks

2015-06-19 05:39:48 -0500 asked a question Which algorithm can detect the face While Robustness against to face rotation

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?

2015-06-04 11:40:39 -0500 commented question how can face recognize with one sample per object

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.

2015-06-04 10:06:36 -0500 asked a question how can face recognize with one sample per object

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؟
