  • Motion estimation with motion vector penalty
    Patent number: 9071844
    Abstract: The MPEG motion estimation process is improved by the introduction of the motion vector penalty. The motion vector employed to encode a macroblock takes into consideration the number of bits needed to encode the macroblock with the selected motion vector. This consideration includes a sum of the residual error and the cost to encode the candidate motion vector. This provides an optimization of the bit allocation and vector type selection. This optimization results in a significantly improved picture quality.
    Type: Grant
