小波变换用于影象分割的研究
摘 要
将近年来兴起的小波理论应用于影象分割技术，提出了一种基于影象直方图小波变换的影象分割方法，并从理论上给出了使用该法所得分割门限的物理意义。实例表明，这种由粗到细引导的多分辨率分析方法，对于复杂影象的分割具有较强的鲁棒性和有效性，克服了传统分割方法中的参数需要人工确定的缺点。

Research on calculation Method of Fractal Dimension Based Topographic Data
() Abstract
The expression and analysis of topographic data is a difficult question to deal with in the automatic treatmenting of topographic data. In this paper, some new calculation methods of fractal dimension based topographic data are proposed after researching general fractal theory, related characters of these methods are discussed and some actual examples are given lastly.
