摘要
近年来,纹理合成技术取得了长足的进步,已成为当前计算机图形学、计算机视觉和图像处理领域的研究热点之一。为使人们对该技术有个概略了解,首先针对纹理合成的研究现状,从合成采样、特征分析与匹配、约束合成和多目标合成等4个方面全面论述了纹理合成目前采用的技术方法;然后从合成质量、合成效率等角度对典型的纹理合成算法进行了分析,并指出了它们的长处和存在的不足之处;最后探讨了纹理合成技术今后的发展方向。
Texture synthesis has been well studied in recent years. It has become an active research topic of computer graphics, vision, and image processing. Aiming at the current progress of texture synthesis, this work we set forth the algorithms based on synthesis sampling, character matching, constrained synthesis and multi-objects synthesis. Further more, we analyze typical algorithms＇ advantage and the disadvantage on the point of synthesis quality and efficiency. At last, we discuss the orientation of texture synthesis and emphasize that the constrained synthesis techniques would speed up the study development and become the key point of synthesis application.
