图像伸长

Classify glass defect by computing rotundity degree and slightness degree as characteristic vector.

最后针对分割图像，提取缺陷目标的面积和周长等特征参数，计算出图像中缺陷的圆形度和伸长度指标，组成特征矢量来对缺陷种类进行识别分类，为进一步的优化玻璃切割系统提供详尽的数据。

Thirdly, it introduces the theory of the imagesegmentation and frequent segmentation technique. The aim of the imagesegmentation is to mark off the interested region of the image, which is done to thecorresponding image processing to reduce the operation time and save the storagespace. At last, it mostly introduces the compress technique based on the wedgelet, andcompares the CART model which is introduced by Donoho and the improved modelby Romberg et.al. with the model of the article, then compares the image ofprocessing based on the three methods.

然后，介绍了图像分割理论和常用的分割技术，图像分割的目的是划分出感兴趣的图像区域，进行相应的图像处理，减少运算时间和节省存储空间；最后，主要介绍了基于伸长小波压缩的技术，将目前主要的算法----Donoho提出的CART模型和Romberg等人基于此的改进模型，与本文所提出的算法模型进行了比较，并对三种方法处理的效果图作了详细的比较。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
