KINECT SKDs:

  1. Kinect SDK 1.0
  2. Kinect SDK Beta
  3. Kinect SDK Beta 2
  4. Kinect SDK 1.5 (1.5.1, 1.5.2)
  5. Kinect SKD 1.6


... and some/many other hacks

All about skeletal data

... and it was fun

EXPLAIN Kinect

Kinect for xBox 360 SDKs (before 1.5)

  • Track two users
  • On distance from 0.8 to 2 meters
  • No gesture support
  • No near mode
  • No face recognition
  • Academic use only


... and it was fun

EXPLAIN Kinect

Kinect SDK 1.5 (Kinect for Windows, February 21)

AND NOW IT'S COOL

EXPLAIN Kinect

Kinect SDK 1.5 (Kinect for Windows)

  • Kinect studio (praise the lord)
  • Human interface guidelines

  • Face tracking SDK

  • Samples and Doc (again praise the lord)
  • Improved skeleton tracking 
  • Performance and data quality enhancements
  • The Joint Orientation (Hierarchical Rotation
    Absolute Orientation)
  • Speech recognition improvement

STILL A MYSTERY?


FACE RECOGNITION

and analyzing

How to start

  • Download Kinect SDK 1.5 and development toolkit

You will get

  • FaceTrackData.dll
  • FaceTrackLib.dll


C++ application can directly use the face tracking libraries

In the other case, you should use a wrapper

Starting projects

Use:

  • Microsoft.Kinect.Toolkit
  • Microsoft.Kinect.Toolkit.FaceTracking

Initialize Sensor and face tracking

kinectSensor.ColorStream.Enable();
kinectSensor.DepthStream.Range = DepthRange.Near;
kinectSensor.DepthStream.Enable(rez80X60);
kinectSensor.SkeletonStream.EnableTrackingInNearRange = true;
kinectSensor.SkeletonStream.TrackingMode = SkeletonTrackingMode.Seated;
skeletonData = new Skeleton[6];
kinectSensor.Start();
faceTracker = new FaceTracker(kinectSensor);
var skeleton = skeletonData.FirstOrDefault(
s => s.TrackingState == SkeletonTrackingState.Tracked);
if (skeleton == null)
    return;
// only track face if all data are there


FaceTrackFrame faceFrame = faceTracker.Track(
kinectSensor.ColorStream.Format, colorPixelData,
kinectSensor.DepthStream.Format, depthPixelData,
skeleton);

Get3DShape()

This method will return 87 face  points in 3D

Emotion analyzer

First there were hits/clicks, then we got likes, but now we can have true emotions.

GetProjected3DShape()

returns the same collection but in a 2D referential corresponding to a 640×480 pixels image.

GetTriangles()

is a method that you can use in association with the Get3DShape method. It will return you a collection of triangles.

Get Animation Unit Coefficients()

 

returns the values

describing the facial expressions.
