Non-photorealistic rendering (NPR) methods have been proposed for gener-Ating stripe-patchwork (SP) images from photographic images. SP images imitate stripe-patchwork, and SP patterns locally change in accordance with shading and edges of pho-Tographic images. We consider that if two SP images are combined, composite SP (CSP) images having a visually interesting effect are obtained. At this time, CSP patterns need to be generated by smoothly connecting two SP patterns. Therefore, we in this paper develop a method to connect two SP patterns by devising the averages of the pixel values of two images in the iterative processing using smoothing filter and inverse filter. We conducted experiments applying our method to various photographic images, and visually confirmed that CSP images in which two SP patterns are smoothly synthesized are gen-erated.
