我正在从事一个检测标志的项目,我目前正在使用haar
培训来获得手部检测。我已经 XML
针对不同的标志训练了文件。我无法XML
在我的检测程序中使用多个文件。无论如何我可以包含不同的XML
文件来检测不同的标志或我可以遵循的另一种方法来检测多个标志
提前致谢。
代码:
if( cascade1)
{
// There can be more than one hand in an image. So create a growable sequence of hands.
// Detect the objects and store them in the sequence
CvSeq* hands1 = cvHaarDetectObjects( img, cascade1, storage,
1.1, 2, CV_HAAR_DO_CANNY_PRUNING,
cvSize(40, 40) );
// Loop the number of hands found.
for( i = 0; i < (hands1 ? hands1->total : 0); i++ )
{
// Create a new rectangle for drawing the hand
CvRect* r = (CvRect*)cvGetSeqElem( hands1, i );
// Find the dimensions of the hand,and scale it if necessary
pt1.x = r->x*scale;
pt2.x = (r->x+r->width)*scale;
pt1.y = r->y*scale;
pt2.y = (r->y+r->height)*scale;
// Draw the rectangle in the input image
cvRectangle( img, pt1, pt2, CV_RGB(230,20,232), 3, 8, 0 );
//text
// Show the image in the window named "result"
cvShowImage( "result", img );
}
}
else if (cascade2)
{
CvSeq* hands2 = cvHaarDetectObjects( img, cascade2, storage,
1.1, 2, CV_HAAR_DO_CANNY_PRUNING,
cvSize(40, 40) );
// Loop the number of hands found.
for( i = 0; i < (hands2 ? hands2->total : 0); i++ )
{
// Create a new rectangle for drawing the hand
CvRect* r = (CvRect*)cvGetSeqElem( hands2, i );
// Find the dimensions of the hand,and scale it if necessary
pt3.x = r->x*scale;
pt4.x = (r->x+r->width)*scale;
pt3.y = r->y*scale;
pt4.y = (r->y+r->height)*scale;
// Draw the rectangle in the input image
cvRectangle( img, pt3, pt4, CV_RGB(230,20,232), 3, 8, 0 );
//text
// Show the image in the window named "result"
cvShowImage( "result", img );
