本文结合DCT变换的特性，利用分形的Peano一hilbert扫描曲线，对基于DCT变换的图像编码方法进行了研究，并提出了改进方法。主要工作分为两个部分: 一是在分块DCT基础上的改进。对分块后生成的各图像块矩阵，不直接作二维DCT变换，而是先进行扫描，使之重排成一维向量，再进行一维DCT变换，这样可以减少运算量。 其次是对层次余弦变换编码部分的改进。使用层次DCT变换与零树编码相结合的方法，并在扫描编码过程中，按Peano一hilbert扫描顺序进行编码。这样不仅可以减少“块效应”，而且可以加快编码速度。-this paper the characteristics of DCT, using fractal Peano a Hilbert scanning curve, the DCT-based image coding method for the study and improvement of methods. The work is divided into two main parts : First, the DCT block on the basis of improvements. Right after block production of the image block matrix, not for direct two-dimensional DCT, but first scan, so they line up in a heavy-dimensional vector and then a peacekeeping DCT, thus reducing the amount of computation. Secondly, the level of cosine transform coding some of the improvements. The use level of DCT and zero tree coding combination of methods, coding and scanning process, according to a Hilbert Peano code scanning sequence. This will not only reduce the "blocking

MoNetBroker是对ESRI MapObjects开发包产品的扩展，它以OCX控件和类型库的方式提供给那些熟悉MapObjects的开发人员，帮助他们利用MapObjects中的数据图层，方便地实现几何网络的连通性分析、非连通分析、两点路径分析、多点路由分析等强大的功能。MoNetBroker可以紧密并方便地与MapObjects相结合，实现高效的网络连通性分析和路径分析等功能。并且具有结点转向和线路单行控制、末梢点线选择等丰富的处理能力。-MoNetBroker of ESRI MapObjects Development Kit product expansion, which was OCX controls and type library available to those familiar with MapObjects developers, to help them use MapObjects the data layer, to facilitate the realization of the geometric network connectivity analysis, non-connected, 2:00 path analysis, multiple points of the road analysis by the powerful functions. MoNetBroker can work closely to facilitate the integration and MapObjects to achieve effective network connectivity analysis and pathway analysis capabilities. And with node shift and line single control point line peripheral rich choice of the handling capacity.
