A Block Matching Motion Estimation Algorithm Based on Wavelet Transform
Ding Run · 2003
The wavelet transform is introduced to low bit video sequences motion estimation. A block matching searching algorithm based on wavelet transform is proposed. The characteristic of the method is that the motion estimation is performed using convertible block according to the size and velocity of the moving object. It unifies the search of matching blocks and points. A modified three steps searching algorithm is developed. The simulation results show that this algorithm has higher precision than three steps searching method and is more suitable for motion estimation of low bit and more detail video transmission.
