Fractal dimension,as a kind of texture feature,is often used for classification.It is important for classification to improve the precision of the fractal dimension.The current method of fractal dimension of image was introduced in the paper.The shortage of the current method was pointed out after analyzing it with the fractal theory.An improved method was proposed then.An experiment result,by comparative analysis on several texture features in a SPOT image,was given.It showed that a more precision result c...
