基于样图的纹理合成技术研究

基于样图的纹理合成方法是继纹理映射、过程纹理合成方法后发展起来的一种纹理技术,用于解决传统方法中出现的缝隙、扭曲、变形和参数调整等问题。在大规模场景的生成以及真实感图形绘制和非真实感绘制、计算机动画等方面具有广泛的应用前景;同时对图像编辑、数据压缩、网络数据的快速传输也有一定的指导意义。该文首先简要回顾了纹理技术的发展历程,总结出基于样图的纹理合成技术的基本原理,从基于Markov模型、侧重逼真显示、任意曲面等几个方面,对基于样图的纹理合成技术进行了较全面的总结和分析,对该领域未来的研究和应用前景做出了有益的探讨。

Study on Texture Synthesis from Samples

Texture synthesis from samples(TSFS)is a new texture technique developed from the texture mapping and procedural texture synthesis.It is efficient to solve the problem which in traditional techniques,such as noticeable seams between texture patches and the stretch and distortion of the pattern when tiling a texture on surfaces.The technique has great potential in real -time rendering for large scale of scenes,realistic and non -photorealistic rendering and computer animation etc.and it imposes instructively on image editing,high ratio data compression,fast data transferring on the Internet.This paper reviews briefly the history of texture technique developing at first,and summarizes the basic theory of TSFS,then comprehensively analyzing TSFS from Markov Random Field model、realistically vision and arbitrary surface.Finally,some existing problems and future work are discussed.
