Functions

void ALVAR_EXPORT alvar::BuildHideTexture (IplImage *image, IplImage *hide_texture, Camera *cam, double gl_modelview[16], PointDouble topleft, PointDouble botright)
 This function is used to construct a texture image which is needed to hide a marker from the original video frame. See SampleMarkerHide.cpp for example implementation.
template<class PointType >
void alvar::DrawBB (IplImage *image, const std::vector< PointType > &points, CvScalar color, std::string label="")
 Draws the bounding box of a connected component (Blob).
void ALVAR_EXPORT alvar::DrawCircles (IplImage *image, const CvSeq *contour, int radius, CvScalar color=CV_RGB(255, 0, 0))
 Draws circles to the contour points that are obtained by Labeling class.
void ALVAR_EXPORT alvar::DrawCVEllipse (IplImage *image, CvBox2D &ellipse, CvScalar color, bool fill=false, double par=0)
 Draws OpenCV ellipse.
void ALVAR_EXPORT alvar::DrawLine (IplImage *image, const Line line, CvScalar color=CV_RGB(0, 255, 0))
 Draws a line.
template<class PointType >
void alvar::DrawLines (IplImage *image, const std::vector< PointType > &points, CvScalar color, bool loop=true)
 Draws lines between consecutive points stored in vector (polyline).
void ALVAR_EXPORT alvar::DrawLines (IplImage *image, const CvSeq *contour, CvScalar color=CV_RGB(255, 0, 0))
 Draws lines between consecutive contour points.
void ALVAR_EXPORT alvar::DrawPoints (IplImage *image, const std::vector< CvPoint > &points, CvScalar color)
 Draws a set of points.
void ALVAR_EXPORT alvar::DrawPoints (IplImage *image, const CvSeq *contour, CvScalar color=CV_RGB(255, 0, 0))
 Draws points of the contour that is obtained by Labeling class.
template<class PointType >
void alvar::DrawPoints (IplImage *image, const std::vector< PointType > &points, CvScalar color, int radius=1)
 Draws circles to the array of points.
void ALVAR_EXPORT alvar::DrawTexture (IplImage *image, IplImage *texture, Camera *cam, double gl_modelview[16], PointDouble topleft, PointDouble botright)
 Draws the texture generated by BuildHideTexture to given video frame. For better performance, use OpenGL instead. See SampleMarkerHide.cpp for example implementation.
