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。
Aiming at several common forms of image degeneration, a spatial domain weighted blind image restoration method based on conjugate gradient method is proposed based on least square method. The experimental results show that this algorithm achieves the restoration of motion blur and out-of-focus blurred images with fewer iterations, and achieves satisfactory results.
