Firstly, the paper, combining the characteristic of synchronous pulse bursts and inhibition with the modified pcnn model, presents a way of finding the foveation points in the images adaptively and effectively, and simulates the human vision system. secondly, pcnn is extended to pcnns, based on the properties of information couple and transmission, an algorithm that is used to fuse images of the same target got by several sensors to an image is presented to simulate the human vision system. thirdly, combining the properties of synchronous pulse bursts, capture, and transmission and competition of waves, the paper presents two ways of classification, one is an algorithm based on the properties of neuron to capture and inhibit to classify the data taking on any complex unlinear distribution robustly, the other is based on the restricted distance and modified of the former to remove the influence of inferior samples in classification ; fin ally, based on the accumulative difference pictures, and the forming and transmission of pcnn wave, selecting and controlling the direction of autowave by connecting the neighbouring neurons selectively, the paper presents a way to simulate the tracks of moving object and detect the moving direction

This software is composed of three modules : the pre - processing, analysis and calculation and post - processing. in the pre - processing, it includes automatic generation of structural meshes, adding contraints and loads and so on ; in the analysis and calculation, the wave - front is used to calculate and establish data files related ; in the post - processing, strong and visual function of vc + + is utilized to display structural deformation graph, contours as well as color cloud pictures. in this last processing, deformation graphs are divided into two types - boundary deformation graph and entire deformation graph in order to show deformation condition entirely ; contour graph comprises isodisplacement graph and isostress graph ; color cloud picture comprises cloud picture of displacement and that of stress, whose drawing principle is isoparametric mapping method
該軟體由三個模塊組成，即前處理、分析計算和后處理。在前處理模塊中，主要包括結構網格的自動剖分、施加約束以及載荷等；在分析計算模塊中，採用波前法計算並形成有關數據文件；在後處理模塊中，利用vc + +強大的可視化功能自動整理計算成果並顯示結構變形圖、等值線圖和彩色雲圖。其中，變形圖分為兩種?外框變形圖和整體網格變形圖，以便能綜合顯示變形情況。 -
I am not joking. the five pictures look so different because they are observed at different wavelengths, namely, in optical, ultraviolet, x - ray, far infrared and radio wave respectively
我不是在開玩笑，這五張照片看來完全不同，是因為它們是以不同波段拍攝，分別是可見光紫外線x射線遠紅外線和無線電波。
