The blind image inpainting problem need to be handle when faced with a large number of images, especially medical images in medical health. For the proposed nonconvex sparse optimization model, a proximal based alternating direction method of multipliers (PADMM) method is designed to solve the problem. Firstly, sparse regularization is imposed to the binary mask since the missing pixels are sparse in our experiments. Secondly, the total variation term is utilized to describe the underlying clean image. Finally, regularization of the fidelity term is used to solve the given blind inpainting problem. Experiments show that this method has better performance than traditional method, and could deal with the blind image inpainting problem.
当面对大量图像时,特别是在医疗健康中的医学图像,需要处理盲图像修复问题。对于所提出的非凸稀疏优化模型,设计了基于近端的交替方向乘子法(PADMM)来解决该问题。首先,由于我们的实验中缺失像素是稀疏的,因此对二进制掩模施加稀疏正则化。其次,利用全变差项来描述底层的干净图像。最后,利用保真项的正则化来解决给定的盲图像修复问题。实验表明,该方法比传统方法具有更好的性能,并且可以处理盲图像修复问题。
