Abstract:
A method, apparatus, and computer program product is present for focusing an image. A spatial model for spatial variation in phase error is identified for the image. The image is divided into a number of subpatches based on the spatial model. Phase correction is applied to each of the number of subpatches to form a number of focused subpatches. The number of focused subpatches is merged to form a focused image.
