Study On Texture Synthesis Algorithm From Examples

Example-based Texture Synthesis was a new way of Texture Synthesis in recent years. It takes small texture image as input to synthesis the arbitrary size texture image. Example-based Texture Synthesis can eliminate some defects of Texture Mapping technique. Moreover, it can avoid the boring processes of Procedural Texture Synthesis. Then, it has become increasingly attractive, and become one of the research hotspots in Computer Graphics, Computer Vision and Image Processing. In this paper, we studied Example-based Texture Synthesis algorithms, proposed some new opinions and algorithms and made a further application.Firstly, this paper reviewed the development of Texture Synthesis algorithms, analyzed typical algorithms of Example-based Texture Synthesis in detail, and illustrated the basic thoughts, features and insufficiencies existed in them.Secondly, this paper analyzed the importance of texture patch's size in Patch-based Texture Synthesis algorithms, investigated the relation between texture relativity feature and texture patch's size. Then, we proposed a novel approach to adaptively adjust texture patch's size, which can work well.Thirdly, this paper analyzed the insufficiency of Patch-based Texture Synthesis, illustrated how to avoid artificial traces between adjacent patch. A novel approach was proposed to seek the best path building on Grapchcut algorithm's merit. The issue was addressed that eyes easily detect the discontinuities along the seams of the patches.Finally, this paper analyzed the Image Mosaic technology. The improved texture synthesis algorithm was applied in Image Mosaic. The experiment results show it works well.
