A novel method was presented to separate defective information from steel sheet surface images by anatomizing the grey values of steel sheet surface images, which uses a classifier composed of some simple perceptrons.

通过对钢板表面信息灰度值的详细分析，提出了一种利用简单感知器组成的分类器识别钢板表面缺陷的新方法。

A text classifier is put between the retrieval interface and retrieving engine. It automatically assorts the retrieval results on-line to divide them to classes of specific topics. So it is convenient for users to find the matching documents to their inquiry.

本文提出在搜索引擎的用户接口与检索器之间接入文本分类器，由它对检索结果进行联机分类，将其划分为若干个具有明确主题的簇，大大方便了用户查找跟查询要求相关的文档。

A novel cascaded and additive model based on cascaded Adaboost classifier is proposed in this paper.

本文提出了一种基于级联Adaboost的''级联--加和''融合算法。

The proposed algorithm first detects smooth intervals based on gray variance from the original frame sequence, then concatenates them to constructs a new frame sequence. After that, video features such as pixel-wise difference, HSV histogram difference and edge histogram difference are fed to a SVM classifier to decide the types of different shot boundaries.

第一级分类器根据视频帧灰度方差特征，将无明显变化的视频序列从原始视频序列中分离出去，得到一个新的视频序列；第二级分类器在新视频序列的基础上，提取视频图像的像素对差值、HSV空间颜色直方图的各分量差值以及边缘直方图X，Y分量差值等视频特征，并采用支持向量机多分类策略进行镜头边界类型的检测。

First, face image is decomposed by two dimension wavelet transform. Then the low frequency subband is convolved with Gabor filters and downsampled by a factor. After that, the kernel principal component analysis is used to reduce the dimension of Gabor features. Finally, minimum distance classifier is used to classify.

首先对人脸进行二维小波分解，通过Gabor滤波器对人脸低频子图滤波，并对Gabor特征进行降采样，然后采用核主分量分析的方法进一步降低Gabor特征的维数，最后采用最小距离分类器进行识别。

The first one is called cursory classifier, which filtrates most of the non-face windows.

所谓人脸检测是指在输入图像中确定所有人脸的位置、大小的过程[6]。

In order to satisfy these requests,"Fluidizing Bed" is selected to install at the bottom of Classifier.

为了满足这个要求，选择流化床安装在选粉机底部。

Because of uniformity of material flow into LV Classifier from Fluidizing Bed. Wear rate becomes smaller for each machine component.

由于物料流从流化床是均匀地进入 LV 选粉机，对于每个机械元件的磨损要小得多。

The material is introduced into LV Classifier after mixing with air / gas completely at fluidizing bed.

物料在流化床与空气/气体完全混合之后进入 LV 选粉机。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
