摘要 针对图像退化的几种常见形式,在最小二乘法的基础上提出了一种基于共轭梯度法的空间域加权盲目图像复原方法。通过实验验证,该算法经过较少的迭代次数就可以实现运动模糊、离焦模糊图像的复原,并取得了较为满意的复原结果。 For several common degradation models, an efficient algorithm based on the least square method was proposed This blind image restoration method uses conjugate gradient algorithm and weighting in space domain. Experiments were designed and performed to simulate the degradation arisen from object motion and defocus. The algorithm was tested by the experiments. After a few iteration steps, the algorithm converges fast and the obtained results are satisfying.
