Because any reports on the active control of rotating disk haven't be seen in China up to now, and this experiment research is important, so the complete set of active control system of rotating disk are built independently. The push-pull type electromagnet is applied to control the vibration of the circular disk. The power amplifier circuit that can respond to wide scope in frequency from DC to AC is designed by improving the existing circuit. The sensor signal is first low-pass filtered, then the proportional control plus the differential control circuit easy used in practice are applied to finish the more effective control. The electromagnetism shield is used as possible to decrease the signal disturbance from the electromagnet to eddy sensor.

In such doing, this dissertation serves as a step stone for papers of its counterparts to come, and, more importantly, it proposes a strategic alternative to the realization of models for image processing. This dissertation consists of three major parts. In the first part, detailed discussions and delicate analyses of academic papers on Cellular Neural Network will be provided in the hope of helping us see the potentiality of Cellular Neural Network in the applications of image processing. I will focus on the aforementioned limitations on hardware compilation as well. In the second part, I will put forth "texture analysis" as one basic model of analysis when we apply Cellular Neural Network to image processing. In this so-called texture analysis, a useful "spatial feature" is especially drawn to help us overcome possible problems of more complicated Cellular Neural Network applications in image processing."Spatial feature" also serves as a well-functioning mechanism for technology of image identification. In the last part of this thesis, I will look into a case study, where Cellular Neural Network is applied to help de-screen document image. Using it as an example, we will see how algorithms of Cellular Neural Network may be of marvelous use in applications in document image processing, since it would reduce a great deal of calculation and computation when applied to software compilation, yet opens up unlimited possibilities for higher-speed hardware compilation of high-level image processing.

这篇论文主要可以分为三大部分:在第一部份里,我们会详细地说明并讨论在过去到现在大部分将分子类神经网路应用於影像处理的相关文献及未来所有可能的发展和技术,另外也将分子类神经网路作一完整的介绍,除此之外,我们也会特别著重於分子类神经网路在影像处理相关应用理论的讨论以及其硬体实现化的考量;在第二部分里,我们提出了一个将分子类神经网路应用於影像辨识处理的基础分析—纹路分析,这是由於纹路分析的复杂性和普遍性会使得分子类神经网路於高阶影像处理的应用不会只局限在单一的影像处理技术,其中我们也提出了一个相当有用的空间特徵,此一特徵不但可以使复杂地高阶影像处理能够应用分子类神经网路,也为影像辨识技术提供了一个很好的辨识机制;在最后一部分里,我们也将文件影像分析做了一个完整的剖析,并以文件影像的去网点为例来说明在实际情况下的分子类神经网路的应用,如此演算法的开发也为文件影像处理提供了更多实际的应用,更考量了文件影像处理若以软体实现时的计算量负荷,而对未来高阶数位影像处理能够以硬体实现来提高处理速度提供了无限的可能。
