| 摘 要： | A novel scheme for image data restoration is proposed in this letter. First, a windowfunction model is exploited to describe the data loss in images. It can change the restoration problem into deconvolution in transform-domain. Then, an iterative algorithm is presented to solve the deconvolution. Because the window-function is available to describe arbitrary shape, our algorithm is suitable for restoring irregular segment of data loss, including square-block. Finally,several simulation tests are done and results prove that the algorithm is valid.
