I have used this package with groovy and a kinect and it works well if you look at the read me file the order_id is the command to add images and retrain the database

Thanx for your help ; I execute the following commands :: 1_roscore 2_roslaunch openni_launch openni.launch 3-rosrun rviz rviz 4-rosrun rqt_reconfigure rqt_reconfigure 5_rosrun image_view image_view image:=/camera/rgb/image_color 6-roscd face_recognition 7-rosrun face_recognition Fserver 8-rosrun face_recognition Fclient till here every thing work , but the rostopic part ,i can't understand how to use it at all . """rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 2 "your_name",,,, rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 1 "none" ,,,, rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 2 "your_friend's_name",,, rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 0 "none",,,, rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 1 "none" ,,,, rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 4 "none" ,,,,"""" Is there any differences will occur if I use Groovy or Fuerte distribution ????

Can you edit your question to add the commands you're running, and maybe spend some time trying to format it so that it's readable?

You have to run the programs from the bin folder also you need to move the other files into that folder from memory the data folder need to be below the bin folder. If you search for face recognition it will have the details make sure you publish the camera in the correct topic. You may need to train the database first to train the database run rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 3 "none" there is no reason to run image_view when you run rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 0 "none" a window will open showing the recognition results

cd to face_recognition/bin then rosrun face_recognition Fserver in another terminal rosrun face_recognition Fclient transfer train.txt, haarcascade_frontalface_alt.xml and the data folder haarcascade_frontalface_alt

make sure the kinect is publishing images to /camera/image_raw you can use rxgraph to see if they are connected. I found it easier to change the topic in face_recognition.ccp and redo rosmake. the none in the other 3 topics is just a place holder. when the server starts what does it print out

@Peter Heim I changed the face_recognition.cpp """" //subscribe to video stream through image transport class image_sub_ = it_.subscribe("/camera/image_raw", 1, &FaceRecognition::imageCB, this) """" after that when I tried to run the ""rosrun face_recognition Fserver"" it printed [ INFO] [1399282787.174585362]: Training data loaded (50 training images of 2 people): [ INFO] [1399282787.174876259]: People: [ INFO] [1399282787.174944313]: <sergio> [ INFO] [1399282787.175038382]: , <pouyan> terminate called after throwing an instance of 'ros::InvalidNameException' what(): Character [ ] is not valid as the first character in Graph Resource Name [ /camera/image_raw].

You have to change it to the topic published by your kinect don't use cut and past type it in i have found that will cause errors. Using rxgraph the face recognition node must connect to the kinect topic or no images will be produced
