| Abstract | Blind restoration is the process of estimating both the true image and the blur from the degraded image, using only partial information about degradation sources and the imaging system. Our main interest concerns optical image enhancement, where the degradation often involves a convolution process. We provide a method to incorporate truncated eigenvalue and total variation regularization into a nonlinear recursive inverse filter (RIF) blind deconvolution scheme first proposed by Kundur and Hatzinakos. Tests are reported on simulated and optical imaging problems. 1 Introduction A fundamental issue in image restoration is blur removal in the presence of observation noise. In the important case where the blurring operation is spatially invariant, then the basic restoration computation involved is simply a deconvolution process that faces the usual difficulties associated with ill-conditioning in the presence of noise [2]. The image observed from a shift invariant linear blurring process,... |
