摘要：

In very low bit rate coding, the amount of bits to encode motion vectors (MV) also takes an important portion in the coded bit stream. A novel criterion for block matching motion estimation is presented in this paper, which gives out a good balance between the motion compensation and motion vector length. Comparing to the widely used SAD (Sum of Absolute Difference) / MSE (Mean Square Error) only criterion-in block-based video coding systems, modified SAD/MSE criterion can provide shorter-coded bits-in overall coding performance under the constant image quality.
