计算机浮雕化处理在动漫图像特效中的应用

On Application of Computer Relief Processing in Cartoon Image Special Effects

为了满足动漫图像的特效制作效果需求,提出了一种基于二维平面图像的计算机浮雕化处理算法.整个算法分为3个关键步骤:(1)依据积分不变量推导每个像素的景深信息,(2)依据梯度压缩和最小二乘法完成景深信息重建,(3)执行高斯双步迭代完成每一个浮雕细节特征的呈现.以柯楠和花仙子两幅动漫图像为实验对像展开实验研究,实验结果表明:该文浮雕化处理算法可以获得逼真的浮雕效果,并在细节特征处有清晰的呈现.同时,该文算法的执行速度也非常快.

In order to satisfy the demand of the effect of animation and cartoon images,a computer relief processing algorithm has been presented in this paper based on two dimensional plane image.The algorithm is divided into three key steps.The first step is based on the integral invariant derivation of each pixel depth information,the second step is based on gradient compression and least square method to complete the reconstruction of depth information,and the third step is the implementation of Gauss double iteration every carving details show.In the Kenan and Hua Xianzi two picture animation image experiments like study,experimental results show that this algorithm can obtain relief of relief effect realistic,and clearly presented in details;at the same time,the algorithm execution speed is very fast.
