An Improved Method for Half Pixel Motion Estimation Using MSE Criteria and Its Realization in DSP
Lin Mi Tao · Journal of Circuits and Systems · 2000
A new algorithm for half pixel motion estimation is proposed when realizing recommendation H.263 for very low bit-rate video compression in DSP. Based on mean square error (MSE) criteria, the computation of half pixel interpolation is unnecessary. Simulation results show its advantage in computation and memory requirement, especially in DSP realization. The compression ratio is increased without degrading the visual quality
