| 摘 要： | 提出一种基于正则化优化修正的电容层析成像图像重建算法。首先利用 Tikhonov正则化法求解系统的逆问题 ,解决逆问题解的不适定性 ;然后利用优化修正法对初始图像进行修正 ,以提高重建图像的质量。实验结果表明 ,该法在重建图像质量和图像重建速率两方面均具有优势。

| Abstract: | An image-reconstruction algorithm based on optimization-revision regularization method for electrical-capacitance tomography is proposed. Firstly, Tikhonov regularization method is used to solve ill-posed characteristic of system inverse problem, then the initial image is revised using optimization revision method. Experimental results show the algorithm has advantages as regards the quality of reconstruction image and the reconstruction rate. |
