分形和自然纹理描述

Fractal and Natural Texture Description

本文在DFBIR场的基础上,提出了利用分形随机纹理模型的纹理描述方法,拓广DFBIR场为各向异性的DFBIR场,指明各向异性的DFBIR场与自然纹理最接近.文中对纹理的产生和分割进行了研究,提出了分割的特征量,并指明分形的标度区,对大量的图像进行了实验研究,实验结果证明了理论分折的正确性,为图像的分割与描述建立了新的途径.

A new method of texture description is proposed using the texture model of fractal random field based on DFBIR. The theory of anisotropic DFBIR field has been extended. It is pointed out that the anisotropic DFBIR field is quite similar to natural image texture. A fractal statistical model for image is developed. The method for estimating the fractal measure and direction measure of the anisotropic DFBIR field is also proposed and has been successfully used in texture description.
