“…Numerical simulations verify that the proposed shifted VFs provide significant improvement in SIR compared to conventional VFs when |v x | > 1 or |v y | > 1 pixels/frame, importantly without compromising the computational complexity. Future work includes extension of the shifted VF architecture to four-dimensional depth filters [22]- [24] and five-dimensional depth-velocity filters [25]- [27] for light field and light field video processing, respectively, in such applications as virtual reality and computational photography.…”

Three-dimensional space-time velocity filters may be used to enhance dynamic passband objects of interest in videos while attenuating moving interfering objects based on their velocities. In this paper, we show that the attenuation of interfering stopband objects may be significantly improved using recently proposed shifted-velocity filters. It is shown that an improvement of approximately 20 dB in signal-to-interference ratio may be achieved for stopband to passband velocity differences of only 1 pixels/frame. More importantly, this improvement is achieved without increasing the computational complexity.
