Target Tracking
What we want
− Object position (3D)
− Object velocity (2D)
− Object size (height / width / length)
− Object type (car / truck /pedestrian / cyclist / motorcyclist)
What we have
− Output from classifiers
− Optical flow
− Stereo information
− Ego motion
− Camera calibration

Detection of Objects
Boosting-based classifiers
Different feature descriptors withincreased complexity
Output given as regions in theimage where objects are detected.

Optical Flow
Match pixels in two consecutiveframes (horizontal or vertical)
Pixel motion gives
− Translation
− Scale change
Must take ego motion intoconsideration

Target Tracking – Difficulties
Lots of objects
Dynamics
− Differ between object types
− Generally unknown
− No initial guess
Measurements
− Missing
− False
Initialize tracks
Execution on embedded system
− Real-time requirements
− Resource constraints

Reflections of Close Collaboration to Industry
Connection of the work to an actual problem and product.
Hands-on experiments with state of the art technology.
Interesting to test algorithms in reality, not only in simulations.
− However, it is not always possible to test on target hardware
