| 摘 要： | 针对图像无线传输缺损严重的问题,本文提出一种基于曲率驱动模型的图像修复算法,该算法首先在梯度域中利用曲率驱动的改进模型对图像缺损区域的梯度进行重建,然后通过求解泊松方程得到修复后的图像。实验结果表明,该算法能有效对图像进行修复。

| Abstract: | In view of problem that the entire blocks of the image are often destoryed in wireless transmission, the paper proposed a image restoration algorithm based on the curvature-driven diffusion (CDD). The algorithm firstly reconstructs the lost data in the gradient domain using improved curvature-driven model, and then obtains the reconstructed image by solving a Poisson equation. The simulation result shows that the algorithm can restore the image effectively. |
