Traditional fractal pattern design has some disadvantages such as being lack of the ability for describing basic cell of pattern and unable to effectively reflect the characters of real scenery. In order to solve the problems

we present a novel pattern design technology of fractal geometry based on image texture rendering. First we improve the texture synthesis algorithm of Wei by using two-dimensional autocorrelation function to analyze the structure and distribution of the texture first

and then determine the size of L neighborhood. Second several special fractal sets are adopted and HSL color space is chosen

so that the fractal structure can be used to manipulate the texture synthesis. The experiments have shown that using the novel technology patterns with different style

color

texture characteristic can be generated quickly.
