Example of tracking with vpGenericTracker.\n\

SYNOPSIS\n\
%s [-i <test image path>] [-x <config file>] [-X <config file depth>]\n\
[-m <model name>] [-M <model name depth>] [-n <initialisation file base name>]\n\
[-f] [-c] [-d] [-h] [-o] [-w] [-l] [-v] [-p]\n\
[-t <tracker type>] [-T <tracker type>] [-e <last frame index>]\n", name);
fprintf(stdout, "\n\
OPTIONS: \n\
-i <input image path> \n\
Set image input path.\n\
These images come from ViSP-images-x.y.z.tar.gz available \n\
on the ViSP website.\n\
Setting the VISP_INPUT_IMAGE_PATH environment\n\
variable produces the same behavior than using\n\
this option.\n\
\n\
-x <config file> \n\
Set the config file (the xml file) to use.\n\
The config file is used to specify the parameters of the tracker.\n\
\n\
-X <config file> \n\
Set the config file (the xml file) to use for the depth sensor.\n\
The config file is used to specify the parameters of the tracker.\n\
\n\
-m <model name> \n\
Specify the name of the file of the model.\n\
The model can either be a vrml model (.wrl) or a .cao file.\n\
\n\
-M <model name> \n\
Specify the name of the file of the model for the depth sensor.\n\
The model can either be a vrml model (.wrl) or a .cao file.\n\
\n\
-n <initialisation file base name> \n\
Base name of the initialisation file. The file will be 'base_name'.init .\n\
This base name is also used for the optional picture specifying where to \n\
click (a .ppm picture).\n\
\n\
-f \n\
Turn off the display of the the moving edges and Klt points. \n\
\n\
-d \n\
Turn off the display.\n\
\n\
-c\n\
Disable the mouse click. Useful to automate the \n\
execution of this program without human intervention.\n\
\n\
-o\n\
Use Ogre3D for visibility tests\n\
\n\
-w\n\
When Ogre3D is enable [-o] show Ogre3D configuration dialog that allows to set the renderer.\n\
\n\
-l\n\
Use the scanline for visibility tests.\n\
\n\
-v\n\
Compute covariance matrix.\n\
\n\
-p\n\
Compute gradient projection error.\n\
\n\
-t <tracker type>\n\
Set tracker type (<1 (Edge)>, <2 (KLT)>, <3 (both)>) for color sensor.\n\
\n\
-T <tracker type>\n\
Set tracker type (<4 (Depth normal)>, <8 (Depth dense)>, <12 (both)>) for depth sensor.\n\
\n\
-e <last frame index>\n\
Specify the index of the last frame. Once reached, the tracking is stopped.\n\
\n\
-h \n\
Print the help.\n\n");

fprintf(stdout, "\nERROR: Bad parameter [%s]\n", badparam);
