Besides, as to inpainting problem in wavelet domain, we introduce a new iterative model. In this model low frequency and high frequency will carry on processing separately, enormous speed up the image repair convergence rate, and even if as high as 90% wavelet coefficient have been lost, this model will also be able to have the very good repair effect. In the old model, to compute the curvature we have to transform the coefficients to the pixel domain, and then transform back to the coefficient domain for several times and this method can solve this problem and speed up the iterative convergence.
其次针对小波域中图像修复的问题,本文提出了一种新的小波域图像修复模型,该模型根据小波变换后系数相关性的特点,将低频和高频分别进行处理,极大的加快了图像修复的收敛速度,并且即使丢失高达90%的小波系数,该模型也会有很好的修复效果,有效的解决了传统的TV- Wavelet模型在计算图像的平均曲率WCURV时,需要反复进行小波分解与重构的计算,迭代速度慢的问题。

The representative minority cultural relic-pottery relic of Buyi minority and the two wooden masks is taken as the research object. Firstly, Hiscanner laser scan detector was adapted for data collection, and then obtain point cloud data which could be recorded on disc for permanent saving was obtianed; Furthermore, the new popular reverse engineering software Geomagic for some disposals of point cloud data was adopted in data condensing, data mending, data filtering, feature line picking up to obtain NURBS surfaces; and then the error between the reconstructed CAD model and the point cloud data was evaluated to guarantee the precision of surface reconstruction to keep the relics keep its original appearance. In the end, the NURBS surfaces are imported to 3D software Solidworks and entities of CAD are generated by surface sewing, mold loft and ablating and other instructions.

In this thesis, how to study and apply of system of CRM based on Web are discussed. Firstly, we summarize the principle of CRM, beginning with the current research condition, and introduce the concept, features and management principle of CRM. Secondly, we illustrate the basic architecture of web-based CRM system to form the basis of the further research and propose the integration of CRM system to the front end of enterprise, namely, the study on the business process re-engineering of CRM system. Then we discuss the key technique knowledge on CRM system based on Web, which included the technology of system interface, system safety and the design of net framework. And explain the technology of web service is a good solution to the problem of system interface in the Internet and the advantage of the develop way based on the B/S pattern. According to an application of CRM system based on Web, this thesis explains how to set up a CRM system based on Web, which include the customer requirement, analyzing the business process, system framework and system safety. At last, this thesis puts forward the extensive foreground of the system of web-based CRM with the expanding of the web technology and explains that there are some questions are to be resolve stilly in this thesis.

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied. Base on chord high difference algorithm, a new one called chord high difference-ratio algorithm is proposed to improve veracity and robusticity of singular points elimination. Then, a registration algorithm based on local surface reconstruction is proposed, which avoids infaust influence coming from single reference point error.
