基于纹理合成技术研究

Texture Synthesis from Samples(TSfS) is a new texture tiling technique developed in latest years, It can efficiently avoid.noticeable seams between texture patches and minimize the stretch and distortion of the pattern when tiling a texture on surfaces, and also can avoid the inconvenient work when using Procedural.Texture Synthesis method. It attracts more and more researcher’s attention and become a hot topic in the field of computer graphics,computer vision and image processing. The technique has great.potential in many applications, especially in image editing, high ratio data compression, fast data transferring on the internet, real-time rendering for large scale of scenes, realistic nd non-photorealisitic.rendering etc. in this project ,we had proposed several new algorithms to solve the problem exsited in the field of texture synthesis study: fast texture synthesis using multiple seeds as.constraints, multi-sample based texture mixing, constrained multi-sample based texture synthesis and texture transfer. With the help of these technologies, new texture samples can be easily obtained by interactive editing the exsiting texture samples and painting styles can be transferred automatically from source images to the target image. Especially the painting styles leaning technology also provides a new idea for the non-photorealisitic rendering.
