纹理图像的多分形特征

Multi-fractal characteristic of texture map

为尽可能保持图像信息的完整,以更好地刻画纹理图像的整体特征,在分析了多分形的基本理论、表示的物理意义和计算方法后,提出了基于多个无标度区的多分形分析方法。这种方法充分利用了图像各个尺度所包含的信息,弥补了传统多分形分析方法因为只选择某一个无标度区计算,而丢失诸多图像信息的不足。运用基于多个无标度区的多分形分析方法对纹理图像进行分析,分析结果对刻画纹理图像的整体特征及对分析复杂结构纹理图像具有指导意义。

To maintain the pictorial information as complete as possible,a new multi-fractal analysis method based on a number of no-scale was put forward based on the basic multi-fractal theory,the physical meaning and the calculation methods were researched.Making full use of the information contained in the images at all scales,this method made up for the deficiencies in traditional multi-fractal analysis me-thods which selected only a certain no-scale basis,so that a lot of information was lost.The proposed method was used to analyze the texture images.The results are meaningful to depicting the whole characteristic of images and analyzing the complex texture.
