Each classifier was linearly combined to give the final identification result. Shape pattern consists of rectangularity, elongation, roundness, sphericity, lobation and seven movement invariants. R, G, B, L histogram and R.G chromaticity histogram were treated as separated color characteristic vector.

A character-codes model based pattern recognition method by using amplitude data of targets frequency response is proposed after the establishment of high frequency response equation of radar targets. The method uses the same unvariant character-codes to express the same target of different angles and uses sequential separating of regions of target's reference variables to obtain multiple coding vectors of all regions for every target. The category and pose of target can be determined after a two-staged classification processing such as coding processing of target range profile data and errors correcting processing of coded data. The two-stage classification results are used to target identification as posterior hypothesis to be tested by sufficient convincing and necessary convincing. The character-codes model based pattern recognition method is also adaptive to variation of target angles and controllable in error probability. Time-consuming and complicated iterative computation is not necessary in the train process of pattern recognition.

Therein, by adopting the ISCSI protocol, the local data storage sub-system constructs the circuital access pattern of the taxation data. The system eliminates the unbalance phenomena between the capability and the demand of the data storage under the traditional bus storage pattern. Under the centralized control pattern, it provides the information access and shares service with the great data volume, the high speed of data transportation and the high availability for the taxation system. By remotely building a backup data center that is totally consistent with the local data center on the IT foundational fabric, the remote data backup sub-system uses the geographical dispersibility of the remote data center and adopts the LVR software replication technology. It implements the synchronous data replication between the local and remote data center, changes the zero standing capability on the great disaster event under the single data center pattern and raises the standing capability on the disaster events for the application and data in the taxation system. By adopting the dynamic replication technology between the heterogeneous data source, the heterogeneous data conformity sub-system successfully shields the various heterogeneous ingredients of the present system.

Aiming at the multiple loop structures in quality management process network, an improved graph pattern mining approach based on Apriori algorithm is put forward, where a frequent pattern of size k, denoted as G, is joined with another frequent pattern of size k, denoted as G, to form a candidate frequent pattern of size (k+1), if there exists a source vertex s in G and a sink vertex e in G such that the graph derived from G by subtracting node s equals with the graph derived from G G by subtracting node e.
