Combining the definition of CWT and the derivative property of convolution, we constructed a general method to calculate the approximate derivative of signal through CWT by using the first and second derivative of Gaussian function, Haar, and the first derivative of three-order-Spline function as wavelets. As compared with the other approaches of calculating derivative, which include the numerical differentiation, polynomial filters, Fourier transform, and the recently proposed DWT method, fast calculation and simple mathematical operation were remarkable advantages of CWT method. For the signal corrupted by severe noise (Signal-toNoise Ratio=5), the satisfactory results could also obtained via CWT method through appropriately adiusting the dilations.

在此基础上，(1)结合连续小波变换的特点和卷积的微分性质，提出了使用Gaussian函数的一阶和二阶导数，Haar和三次样条函数的一阶导数作为小波函数的连续小波变换计算信号近似导数的一般性方法，与其他导数计算方法(包括数字微分法，多项式滤波法，Fourier变换法和离散小波变换法)相比，本法简单便捷，计算速度快，对于噪声含量较高的信号(S/N为5)，只要适当调节尺度即可获得比较满意的结果。

Secondly, in this paper, it described and analyzed the segmentation method based on the edge in the domain of image segmentation in detail. It did experiments on several edge detection operators using MATLAB, it summarized the advantage and the shortcoming of traditional edge detection operators, and the operating environment. On the basis of the experimental analysis, it implemented an edge location more precise, more efficient operating speed edge extraction method——Template Vector. In this method, it optimized differential approximate calculation of first differential operators the paper mentioned. After experimented on this edge extraction method, contracted with the traditional methods, the edge outline is extracted more accurately and more exquisitely, furthermore, it retained the object outline furthest, and achieved more satisfied edge extraction result.

Taking the administrative villages as units, a comprehensive and detailed survey was made to attain the rich and reliable data, including the information about the status of the land use, the relationship of the land supply and demand, the living standards of farmers and the minimum of urban resident living guarantee and so on. Then the estimating system was established. Afterwards, basing the survey and the system, the character of each unit was transfer into data. And, utilizing the frequency law, the whole county was divided into four expropriation land blocks. The area was measured and the map, showing the differences between blocks, of the Arable Land Blocks for expropriation of Siyang was protracted by the method of GIS. Finally, the land expropriation price is calculated by agricultural land economical function compensate method and urban construction land criterion price avulse method, then the price was tested by expropriation case comparison method. It is beneficial not only for protecting farmers rights and interests, but also for link up with the current land compensate standard, so this way to calculate the land expropriate price is more reasonably.
