| 摘 要： | INTRODUCTIONIn the last two decades, research on fractal ge-ometry has received much attention for its theoretical significance and practical applications. Pattern design based on fractal geometry is an important application area of fractal techniques in the textile industry (Wang, 2003). Computer aided pattern design involves the de-sign of textures and colors in the pattern. The source of textures is rich. All kinds of objects and scenery including man-made abstract objects can be used…

| Abstract: | Traditional fractal pattern design has some disadvantages such as inability to effectively reflect the characteristics of
real scenery and texture. We propose a novel pattern design technique combining fractal geometry and image texture synthesis
to solve these problems. We have improved Wei and Levoy (2000)’s texture synthesis algorithm by first using two-dimensional
autocorrelation function to analyze the structure and distribution of textures, and then determining the size of L neighborhood.
Several special fractal sets were adopted and HSL (Hue, Saturation, and Light) color space was chosen. The fractal structure
was used to manipulate the texture synthesis in HSL color space where the pattern’s color can be adjusted conveniently. Experiments
showed that patterns with different styles and different color characteristics can be more efficiently generated using the
new technique.
