摘　　要：为模拟植物在不同季节的颜色变化,提出一种在虚拟环境中实现对不同季节植物表观仿真的方法。采用基于二阶统计量的全局颜色传递算法,得到不同季节的纹理库;基于生成的纹理库实现对不同季节植物的表观仿真。为改善传递效果,引入高阶矩,调整目标图像的斜度和峰度分布,使之与样本图像一致。建立评估模型,从颜色和纹理两方面对传递效果进行评估,评估结果表明,该方法的仿真效果较好。To simulate the color change of plants in different seasons, a new method simulating appearances of plants in different seasons in the virtual environment was presented. Firstly, the global color transfer algorithm based on second order statistics was used to obtain the texture library for different seasons. Then the simulation of plants in different seasons was implemented based on the texture library. To improve the transferring effect, the high order moment was introduced and the angle and kurtosis distribution of the target image were adjusted, so that it could be consistent with the sample inaage. To evaluate transferring effects, an evaluation model was established con- sidering color and textur~ Simulation results show that the method obtains satisfied simulation results.
