  • To realize the motion vector estimation targeted at moving objects in video, the motion estimation system based on transformation domain of multi-dimensional vector matrix is established. The research is then carried out in transformation domain to study on multi-dimensional energy concentration plane formed by moving objects in moving videos. Firstly, the theory of multi-dimensional vector matrix and transformation are introduced. Then the theoretical derivation of energy concentration plane in transformation domain formed by moving objects is presented. The next step is to calculate the motion vector using plane fitting method. Finally,the performance and iteration speed among a few methods are analyzed. Experimental results show that the motion vector accuracy obtained by moving plane fitting in multi-dimensional vector matrix transformation domain can reach 10-2 pixel. A new high accuracy motion vector estimation method in transformation domain is provided.
