| 摘 要： | 研究了分维数理论在图像特征提取上的应用，在分析图像分维数计算原理的基础上，提出了一种计算分维数及其辅助特征的方法，并进而研究噪声、遮挡及图像灰度对比度对分维数值的影响。实验结果表明，分维数反映了图像的纹理性质，加入图像噪声、云层遮挡或提高图像对比度都会使分维数不同程度的增大。

| Abstract: | he application for the fractal dimension theory in image feature extraction is studied.Anew method for estimating the fractal dimension from image surfaces based on the fractal di-mension computation principle is presented.The effect of noise,occlusion and image con-trast on the fractal dimension is analyzed.Experimental results show that the image texturecan be demonstrated bv the fractal dimension and the fractal dimension will in increase in acertain degree if the image noise and the occlusion by clouds are taken into account or whenthe image contrast increases. |
