摘要
A reconstruction method is presented to deal with spatially misaligned and turbulence degraded images that contain shift and rotation motion. This method is implemented through bringing the channels into spatial alignment via image registration and then restoring the original images by a new multiframe blind deconvolution. A frequency domain technique is introduced to precisely register the spatially misaligned images. New priori information of temporal signatures is adopted to constrain the solution in the blind deconvolution. Results show that by the proposed method high quality image can be recovered from spatially misaligned and turbulence degraded images. Crown Copyright (C) 2011 Published by Elsevier Ltd.
