| 英文摘要 | In this paper, we consider the nonnegatively constrained multichannel image deblurring problem and propose regularizing active set methods for numerical restoration. For image deblurring problems, it is reasonable to solve a regularizing model with nonnegativity constraints because of the physical meaning of the image. We consider a general regularizing l(p) - l(q) model with nonnegativity constraints. For p and q equaling 2. the model is in a convex quadratic form, therefore, the active set method is proposed since the nonnegativity constraints are imposed naturally For p and q not equaling 2, we present an active set method with a feasible Newton-conjugate gradient solution technique. Numerical experiments are presented for ill-posed three-channel blurred image restoration problems. (C) 2009 Optical Society of America |
