文中介绍了该算法的原理并对电力设备红外离焦图像处理结果进行了分析。
The principle of the algorithm was introduced and the results of the algorithm to deal with the infrared defocused image of electrical device were analyzed.
然而，由于重构出的目标图像中叠加了前景遮挡物的离焦图像，因此其对比度受到严重影响。
However, the reconstructed images suffer from degraded contrast due to the superimposition of foreground defocus blur.
相位变更（PD）方法是一种基于两个或多个不同离焦面图像来恢复光瞳畸变波前相位的光学波前传感技术。
Phase diversity(PD)is a kind of wavefront sensing technique based on the measurement of two or more object images.
