In the article, a more efficient motion vector tree (MVT) pruning method targeted at the reduction of the amount of motion information is introduced. The proposed method uses a new rate-distortion pruning strategy for MVT. MC-EZBC is a fully scalable video codec, which supports quality/bit-rate, spatial and temporal scalabilities. It uses a motion-compensated temporal filtering (MCTF) and embedded zero-tree block coding (EZBC) to generate fully embedded bit-stream. Compared with the original MC-EZBC, the improved MC-EZBC with the new MVT pruning method can significantly improve the performance at low bit-rate.
