%X In order to deal with the non-topology preservation occurred in transformed results, this paper proposed an approach of topology preservation transformation based on densely landmarks. Firstly, it needed to locate the local region which was not topology preservation. Then, determined the direction angle of the region. Next, the proposed approach determined and deleted the landmarks which caused the non-topology preservation. Finally, generated the topology preserving results by the optimal landmarks. Experimental results show that the proposed method can effectively address the problem of non-topology preserving under densely landmarks. Moreover, experiments also demonstrate the good performance of the proposed method.
