The development of intelligent system which accorded with human cognitive mechanism will exert a profound influence on national defense  economy  education  culture and etc. A computer simulation method according with cognitive mechanism of human vision was proposed on the basis of Structural Decomposition Theory. Many basic shape feature information tables of similar object from different side can determine a kind of object uniquely. System weighted basic shape features in two different information tables by membership degree and then calculated similarity. The identifying object which had the maximum similarity with it in system was what we needed. The system used 83 pictures of 6 kinds of objects with different side for training and testing. The experiment results demonstrated  task of basic shape extraction  object recognition and others can be completed effectively with the method in paper. The method in paper can be a new attempt on computer simulation method according with cognitive mechanism of human vision from cognitive field. 2010 Crown Copyright.

Current research on infrared simulation often focuses mainly on infrared imaging simulation by computer and pays little attention to outdoor simulation of infrared radiation characteristics of targets. In order to simulate infrared radiance of targets outdoors  in this paper we propose a new outdoor simulation method on the basis of heating the cloth by electricity. There are two major contributions in the paper. Firstly  uneven distributing of temperature field of the cloth surface is considered and the long-wave thermal imager is used as a link of the temperature control system. On the basis of many experiments  the expression is concluded about the relation of the temperature obtained by the lone-wave thermal imager and the temperature obtained by the temperature control system and the environmental temperature at the experimental scene. Secondly  the influence of the environment at the experimental scene on the infrared radiance of the cloth surface is thought over. Thanks to two measures above  simulation precision of infrared radiance is made much better. The results of many outdoor experiments demonstrate the performance of the proposed approach. 2009 SPIE.
