Motion parameters estimation by new propagation approach and time-frequency representations

Estimation of time-varying motion parameters of moving objects is considered. The motion parameters are mapped into the instantaneous frequency (IF) of a frequency modulated (FM) signal. The IF estimation is obtained using the Wigner distribution (WD). Generalization in the case of multiple objects and reduced interference distributions is given. A new propagation approach is proposed for joint estimation of velocity and position of objects in a video-sequence. This approach produces better accuracy than the one based on the variable μ-propagation-based one.
