The method obtained multiple training samples from a single face image by multi channel sampling before two-dimensional independent component analysis transformation. Experimental results on the ORL face database and YALE face database show that the proposed method is feasible and has higher recognition performance compared with GREY, PCA, ICA, 2DICA, projection combined PCA, FLDA, sampled FLDA and other algorithms where only one sample image per person is available for training.

Several experimental applications have been developed finally. In this paper, there areinnovations from the following four aspects:1. Definition and research methods of current distributed system and distributedinteractive simulation system follow those of traditional parallel computing system.While this paper points out it is one-sided to measure the scalability just from thenumber of processors and performance of a system, because the resources of distributed systems are heterogeneous and they can be used in diverse applications. Inthis paper, scalability of distributed interactive simulation platform is defined as theability of scaling (including scale-up and scale-down) in functionality and performanceof systems which is run on the platform when number of processors and otherhardware resources such as network change, i.e. when problem size is scaled up and system resources is increased, the performanceremains fixed and it is easy to expand the functions of simulationapplications.

Finally, the query processing algorithm based on the load balance data storage method makes all nodes within a ring cooperatively answer the user's query. Although the ring based load balance data storage method and the query processing algorithm consume more energy than the traditional method when answering a user's query, the method makes all nodes within the network consume energy evenly, which avoids the hotspot problem of the traditional method, so the lifetime of sensor networks can be extended.

基于环的负载平衡数据存储协议以及基于此存储协议的查询处理算法虽然在查询处理中所消耗的能量高于传统方法，但可以保证从数据存储到查询处理的整个过程中，网络的所有节点均匀地消耗能量，从而避免了传统方法中的热点问题，达到延长网络寿命的目的。
