    <p>I am trying for object detection using opencv 2.4.2. Here is the code for my moving foreground subtraction. Now I want to detect moving object in original frame and draw bounding box around it. can anybody please help me? how to do that?</p> <pre><code> #include "stdafx.h" #include "opencv2/imgproc/imgproc.hpp" #include "opencv2/highgui/highgui.hpp" #include "opencv2/contrib/contrib.hpp" #include "conio.h" #include "time.h" #include "opencv/cvaux.hpp" #include "opencv2/core/core.hpp" #include "opencv2/calib3d/calib3d.hpp" using namespace std; using namespace cv; int main(int argc, char *argv[]) { int key = 0; CvSize imgSize; CvCapture* capture = cvCaptureFromFile( "S:\\offline object detection database\\TwoEnterShop2cor.MPG" ); IplImage* frame = cvQueryFrame( capture ); imgSize = cvGetSize(frame); IplImage* grayImage = cvCreateImage( imgSize, IPL_DEPTH_8U, 1); IplImage* currframe = cvCreateImage(imgSize,IPL_DEPTH_8U,3); IplImage* destframe = cvCreateImage(imgSize,IPL_DEPTH_8U,3); if ( !capture ) { fprintf( stderr, "Cannot open AVI!\n" ); return 1; } int fps = ( int )cvGetCaptureProperty( capture, CV_CAP_PROP_FPS ); cvNamedWindow( "dest", CV_WINDOW_AUTOSIZE ); while( key != 'y' ) { frame = cvQueryFrame( capture ); currframe = cvCloneImage( frame );// copy frame to current frame = cvQueryFrame( capture );// grab frame cvAbsDiff(frame,currframe,destframe); cvCvtColor(destframe,grayImage,CV_RGB2GRAY); cvSmooth(grayImage,grayImage,CV_MEDIAN,3,3,0); cvAdaptiveThreshold(grayImage,grayImage,230,CV_THRESH_BINARY,CV_ADAPTIVE_THRESH_GAUSSIAN_C,3,5); cvDilate(grayImage, grayImage, 0,1); cvErode(grayImage,grayImage, 0, 0); if(key==27 )break; cvShowImage( "fram",currframe); cvShowImage( "dest",grayImage); key = cvWaitKey( 100 ); } cvDestroyWindow( "dest" ); cvReleaseCapture( &amp;capture ); return 0; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
