摘要
介绍了一种利用归整化对数表提取图像分形特征的快速方法．该方法在计算图像的局部分维数和局部分形模型拟合误差时，通过查表的方式获得对数运算的数值，避免了对数的在线计算，同时使计算时间大大缩短．该算法为用现有硬件实现图像分形特征的实时提取创造了先决条件．
A fast algorithm for extracting fractal features of an image by a normalized logarithm table is presented. In the algorithm the value of a logarithm manipulation is obtained in the looking up table manner when computing the local fractal dimension and fractal model fit error of an image, the on line computation of the logarithm is avoided and at the same time the computing time is reduced greatly. The algorithm makes it possible that the fractal features of an image are extracted in real time in the existing hardware environment.
