Research On Analogy Painting Design Based On Texture Synthesis

Chinese landscape painting begins from the Sui Dynasty, has a long history. Since landscape painting separated from portraits, it still lives at the present. However, due to its complex artistic painting style, how to use computers to learn their style has been a challenging task in the field of computer arts. Texture synthesis in computer graphics which is an important technology has a wide range of applications in computer arts. In recent years, the idea of analogy is applied to the image artistic style learning and achieves good results. This paper firstly analyzes the classical texture synthesis algorithm, then introduces the idea of image analogy into it, finally, proposes a analogy paintings designed algorithm based on texture synthesis. The main work of this paper is as follows:First, introducing some classic texture synthesis algorithms, elaborate ideas and steps of algorithm, analyzing the advantages and disadvantages of each algorithm and its application features.Second, based on the traditional block stitching texture transfer algorithm, propose a texture transmission algorithm with edge information. Since the target block edge information is not considered by the original algorithm in the process of search matching block, in the final synthesis result diagram, the edge information is not clear, and, for some structural texture, it destructs the texel structure. The improved algorithm increases information processing items in the original search error matching formula by calculating the gradient of the edge. Meanwhile, the entire transfer process introduces a luminance remapping matching pretreatment strategy. Experimental results prove that the improved method can achieve better experimental results.Third, with the idea of the image analogy, we propose an analogy paintings designed algorithm based on texture synthesis. During designing the painting, with the idea of image analogy, the image segmentation technology is used into the algorithm in order to obtain the source analogy designs. At the same time, through classifying the Chinese landscape painting in accordance with its different composition styles and creating a user template library for users to choose, we propose a new user map generation algorithm to solve the real problem that too difficult to obtain a sample FIG. Finally, combined with improved texture synthesis and texture transfer algorithm, we achieve the ultimate analogy style painting designs.In this paper, through building user template library, drawing on images analogy ideas, introducing image segmentation and regional connectivity technology, based on the traditional texture synthesis and texture transfer algorithm, we achieve a landscape design system. Meanwhile, based on the conventional texture transmission method, we propose a improved texture transmission algorithm with the introduction of edge information and apply it to the landscape design system. Mass experiments results prove effectiveness of the improved algorithm and the landscape design system.
