ActiveUS20080137957A1Low face detection speedLow efficiencyCharacter and pattern recognitionFrame basedMean-shift
The present invention discloses a method of automatically detecting and tracking a face by an electronic capturing device that alternatively uses a face detecting algorithm to quickly locate a face in a frame based on a skin color model and a face tracking algorithm to locate a face in subsequent frames by a nonparametric technique and a mean shift algorithm. If the face tracking algorithm cannot track and locate a face correctly, the face detecting algorithm will be used again to detect a face position in another new frame until the face position is located successfully, and then the face tracking algorithm will be used again for detecting and locating the face position in subsequent frames. After this method has detected a face position, a variable focal lens is used to slowly and smoothly refocus the frame including a face region, so as to obtain a clear face image.

A method and device for locating the position, on the right or on the left, of a vehicle wheel. The wheel is equipped with two magnetic sensors having axes of maximum sensitivity lying in a plane that is secant to the axis of rotation of the wheel and which are offset from one another in this secant plane by a predetermined angle θ. As the vehicle moves in a given travel direction, a signal generated by the variation in a magnetic field is measured at the terminals of each of the magnetic sensors to deliver two periodic signals phase-shifted from one another by an angular value equal to (+ or −) θ, this phase shift is used to determine the direction of wheel rotation, and from such direction and the travel direction, the location, on the right or on the left, of the wheel is deduced.
