摘要:

我们提出了一种新的方法来图像复原,利用本地化的结构化预测和非线性多任务学习的想法。我们优化了惩罚的能量函数正则化的一个总和的条款测量补丁之间的距离要恢复和清洁补丁从外部数据库收集事先。由此产生的估计来利用重叠补丁的局部依赖性属性的强大的统计保证。我们推导出相应的算法的能量的基础上的均方误差和欧几里得范数误差。最后,我们证明了我们的模型对不同的图像复原问题的实际有效性,使用标准的基准。

英文摘要:

We present a novel approach to image restoration that leverages ideas from localized structured prediction and non-linear multi-task learning. We optimize a penalized energy function regularized by a sum of terms measuring the distance between patches to be restored and clean patches from an external database gathered beforehand. The resulting estimator comes with strong statistical guarantees leveraging local dependency properties of overlapping patches. We derive the corresponding algorithms for energies based on the mean-squared and Euclidean norm errors. Finally, we demonstrate the practical effectiveness of our model on different image restoration problems using standard benchmarks.
