Hello.

1) In order to do that, first check the "openni" tutorial. This tutorial demonstrates how to open a Kinect in ROS, introduces ROS tools for visualization and configuration, etc: http://wiki.ros.org/openni_launch/Tutorials/QuickStart

2) Then, also check how to use a bridge between the kinect image topic and Opencv. This tutorial describes how to interface ROS and OpenCV by converting ROS images into OpenCV images, and vice versa, using cv_bridge. Included is a sample node that can be used as a template for your own node: http://wiki.ros.org/cv_bridge/Tutorials/ConvertingBetweenROSImagesAndOpenCVImagesPython

3) Read the OpenCV documentation on how to recognize faces: http://docs.opencv.org/trunk/modules/contrib/doc/facerec/index.html http://docs.opencv.org/trunk/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html

3) Try some example that you can found on the web, like this (I haven't tried it): https://code.google.com/p/ros-by-example/source/browse/trunk/rbx_vol_1/rbx1_vision/nodes/face_detector.py?r=116

I hope this links can help you, good luck!

If you want to do true face recognition rather than simple face detection, and you want to use ROS, check out the most excellent cob_people_detection packages. These packages take full advantage of the depth information from the Kinect to first look for "head-like" blobs which are likely to contain faces. You can then train the system to recognize different faces by giving each face a name and taking a number of snapshots from different angles.

when I try to execute cob_people_detection and try to know requirements for the package""" rosdep cob_people_perception-fuerte_dev"" the following requirements appear :: """ rosdep check <stacks-and-packages>... check if the dependencies of package(s) have been met. rosdep install <stacks-and-packages>... generate a bash script and then execute it. rosdep db generate the dependency database and print it to the console. rosdep init initialize rosdep sources in /etc/ros/rosdep. May require sudo. rosdep keys <stacks-and-packages>... list the rosdep keys that the packages depend on. rosdep resolve <rosdeps> resolve <rosdeps> to system dependencies rosdep update update the local rosdep database based on the rosdep sources. rosdep what-needs <rosdeps>... print a list of packages that declare a rosdep on (at least one of) <rosdeps> rosdep where-defined <rosdeps>... print a list of yaml files that declare a rosdep on (at least one of) <rosdeps> """???
