摘　　要：动态纹理综合技术是近年来计算机图形学领域研究的热点与难点之一。动态纹理综合技术在虚拟现实、电脑动画等领域有着广泛的应用。将Kernel PCA算法引入到动态纹理的分析与综合中,并与传统的基于线性PCA的动态纹理算法相比较。实验数据表明,基于Kernel PCA的改进算法在动态纹理描述和综合效果上均比线性PCA算法更好。Dynamic texture synthesis technology is one of the hotspot and difficulty in computer graphics which has wide application in virtual reality, computer movie etc. A novel method--Kernel PCA, is introduced to analyze and synthesize dynamic texture and a comparison with traditional, linear PCA-based method is made. Simulation results show that our improved algorithm has better performance than the LDS-based method.
