A hybrid pattern recognition system mainly composed of a new analogue image processing technique has been proposed and developed to identify simultaneously and instantaneously the shape and position of multiple objects displayed on liquid crystal monitor via CCD camera. The analogue image processing technique is composed of the both multiplexed matched spatial filter(MMSF) technique and the incoherent-coherent image converting technique, and is quite different from the present image processing technique. The fundamental and developmental research had the result of obtaining useful knowledge and view as follows.(1) It is clarified to be able to identify the different over 36 shapes of alphabetical and numerical letters simultaneously and instantaneously by a MMSF.(2) When this MMSF is used, it is easy to measure the position, size and number of each shabes of objects simultaneously.(3) It is clarified that photoconductor-plastic hologram with solvent vapor processing is the most suitabl … More e for matched spatial filter, for the reason that photoconductor-plastic with solvent vapor processing do not give the distortion for the hologram and the setting position of hologram do not change in the development processing of photoconductor-plastic.(4) At the off-line shape identification system using TV image, although Liquid Crystal Display(LCD) having coarse dotts was used as coherent image convertor, it produced a good results exceeding our expectations for identification of shape, when photoconductor-plastic was used for the hologram.(5) However, the LCD composed of coarse dotts have a bad effect on conversion of image, so it is better for us to use the coherent image convertor having fine dotts and sharp image profile.(6) Shapes and positions of different nine letters was identified simultaneously in about 2 seconds. However it is clarified that many different shapes and positions of objects can be measured instantaneously, when exclusive circuits are used for hybrid data processing of each output bright spot and suitable language are used to the data processing.

提出并开发了一种混合模式识别系统，该系统主要由一种新的模拟图像处理技术组成，可以同时、即时地识别CCD摄像机显示在液晶显示器上的多个物体的形状和位置。模拟图像处理技术由多路匹配空间滤波（MMSF）技术和非相干相干图像转换技术组成，与现有的图像处理技术有很大的不同。基础和发展研究的结果是获得了以下有用的知识和观点。(1)阐明了MMSF能够同时、瞬间识别36种以上不同形状的字母和数字字母。(2)当使用该MMSF时，可以方便地同时测量物体各形状的位置、大小和数量。(3)溶剂蒸汽处理的光导体-塑料全息图在光导体-塑料显影过程中不会造成全息图的畸变，全息图的设置位置也不会发生变化，因此确定了溶剂蒸汽处理的光导体-塑料全息图最适合用于匹配空间滤波器。(4)在使用电视图像的离线形状识别系统中，虽然使用带有粗点的液晶显示器（LCD）作为相干图像转换器，但当使用光导体塑料作为全息图时，其形状识别效果超出了我们的预期。(5)然而，由粗点组成的LCD对图像的转换效果不好，因此我们最好使用具有细点和清晰图像轮廓的相干图像转换器。(6)在2秒左右的时间内同时识别出不同的9个字母的形状和位置。然而，当使用专用电路对每个输出亮点进行混合数据处理并使用合适的语言进行数据处理时，阐明了可以瞬间测量许多不同形状和位置的物体。少
