Abstract EN
The temporal complexity of video sequences can be characterized by motion vector map which consists of motion vectors of each macroblock (MB).
In order to obtain the optimal initial QP (quantization parameter) for the various video sequences which have different spatial and temporal complexities, this paper proposes a simple and high performance initial QP determining method based on motion vector map and temporal complexity to decide an initial QP in given target bit rate.
The proposed algorithm produces the reconstructed video sequences with outstanding and stable quality.
For any video sequences, the initial QP can be easily determined from matrices by target bit rate and mapped spatial complexity using proposed mapping method.
Experimental results show that the proposed algorithm can show more outstanding objective and subjective performance than other conventional determining methods.
