提出了一种新的适用于移变降质图像复原的算法——能量约束自适应迭代复原。算法采用能量约束复原的空域迭代形式, 使其能够用于处理光学像差引起的移变降质复原问题；以局部能量约束取代总体能量约束, 使算法具有空间自适应特性；并采用双通道处理方法, 消除能量约束带来的图像亮度衰减, 同时抑制图像边界截断引起的振荡波纹。场曲复原仿真实验结果表明, 算法对移变降质图像有良好的复原效果。

A new restoration algorithm, energy constrained adaptive iterative restoration, is proposed for restoring space-variant degraded images caused by the optical aberration. Space domain iteration of energy constrained restoration is used to solve the space-variant restoration. The algorithm is adaptive due to using local constrain instead of total constrain. And 2-channel restoring removes the image intensity loss and depresses the ringing caused by border cutting off. The result of a field-curve restoring simulation indicates that the algorithm is effective for the space-variant degraded images.
