| 摘 要： | 采用对深度图像自适应分层滤波方法，提出三维掩模的概念，基于Z－buffer把深度图像分解成若干个不相交的子图像，通过对子图像的滤波与合成，降低算法的复杂度，并使滤波后的误差控制在给定范围内，为计算机渲染算法提供了一种新的后期处理途径，并可应用于景深与运动模糊的模拟．

| Abstract: | With a new adaptive stratified filtering method for the depth image based on Z-buffer, the concept of 3-D mask is proposed. It is proved that the algorithm complexity is reduced and the postfiltration error is controlled within a given range by splitting the depth image into several non-intersected subimages which are then filtered and composed. This method has been successfully used in the computer graphics rendering algorithm. |
