In this paper , a high integrated and intelligent digital dsp - spm system is developed based on the nspm6800 spm manufactured by the beijing zhongke mechanical & electrical equipment co . at present , the pc of spm system is burdened with not only sending and receiving data , but also disposing of image , which hinders the enhancement of speed of the system . in addition , as the function of spm is expanding , including tappingmode afm , efm , mfm , scm , etc , one hand , it amplifies the range of the application of spm , on the other hand it also means that the task of autocontrol and data transfer heavier . the advantages offered by the dsp compared to analog systems include considerable flexibility in the choice of the signal processing algorithm and greater ease in managing control parameters by the host computer , which are very important for the improvement of spm 本课题以北京市中科机电设备公司的nspm - 6800型扫描探针显微镜为基础，重新设计了以dsp为控制核心的控制系统，主要解决原系统存在的以下问题： ( 1 ) pc机既要实时控制数据的采集与发送，又要进行图像的后处理，整个系统的实时性难以达到要求； ( 2 )随着spm功能的扩展，一方面包括轻敲式原子力显微镜、电场力、磁场力、扫描容场显微镜等技术在内的spm技术扩展了仪器的测试范围和功能，另一方面也意味着自动控制量的增加和数据处理量的增加； ( 3 ) 16位a d 、 d a都采用的是购买的板卡，也通过isa槽插在pc机内，成本高，不利于扩展； ( 4 )另外，数字板通过isa槽插在pc机内，易受于扰，而且给安装带来不便。
Svm and its implementation technique smo can be used for image retrieval ; however , they were originally developed for dealing with two - classification problem , so a binary tree and a matrix for classification are constructed for solving multi - classification problem . feature vectors can be com 因为svm只能够用于两类分类问题，本文构建了二叉树分类器，将svm技术扩展到多类别分类领域当中；利用前述的图像颜色特征、纹理特征和形状特征作为输入向量，通过训练得到支持向量，构建多类分类函数，进行图像检索。
