三维立体动画增强图像处理效果仿真研究

Simulation Research on 3D Animation Enhanced Image Processing Effect

对三维立体动画增强图像处理效果优化的研究,能够有效改善图像视觉效果。对三维立体动画的增强,需要对三维立体动画亮度均匀度进行归一化处理,计算特征信息对比度增强的最小放大因子,完成对三维动画的增强。传统方法计算图像非线性变换参数,抑制特征信息噪声的增强,但忽略了计算特征信息对比度增强的最小放大因子,导致图像处理效果不理想。提出基于灰度均匀度的三维立体动画增强图像处理效果方法,首先利用双边滤波器对三维立体动画特征信息进行平滑处理,计算三维立体动画局部区域内灰度值的离散变化程度和亮度分布的4阶矩;对三维立体动画特征区域的亮度均匀度进行归一化处理;最后计算特征信息对比度增强的最小放大因子,实现三维立体动画增强图像处理效果。仿真结果证明,利用上述方法能够获得更加理想的三维立体动画增强效果。

ABSTRACT ：This paper proposes a method for image treatment effect of three-dimensional cartoon enhancement based on gray uniformity. Firstly, bilateral filter is utilized to smooth characteristic information of three-dimensional cartoon, discrete variation degree of gray value in local area of three-dimensional cartoon and four order matrix of brightness distribution are calculated, and then brightness uniformity for characteristic region of three-dimensional cartoon is normalized. Finally, the minimum magnification factor for contrast ratio enhancement of characteristic infor- mation is calculated. Image treatment effect of three-dimensional cartoon enhancement is achieved. The simulation results demonstrate that the proposed method can obtain good effect for three-dimensional cartoon enhancement.
