提出一种基于RGB-D的深度图像空洞修复算法。通过改进的双边滤波对深度图进行滤波处理,填充了空洞而且保持了图像的边缘;再利用复合型中值滤波对深度图进行处理消除孤立点的影响,平滑了深度图像。实验结果表明,这一方法能够有效地对深度图进行空洞修复且图像边缘清晰。
A new algorithm to fill the depth map was proposed.The improved the bilateral filtering was put forward for edge preserving to solve the edge in the final depth map and the hole in the depth map.The complex median filtering was used to smooth the depth map and to eliminate the influence of the outlier data.Experimental results show that proposed method can effectively fill the hole in depth map.
