修正的谱共轭梯度算法在图像恢复中的应用
A modified spectral conj ugate gradient method and its applications in image restoration
摘要
Abstract
Based on the classic conj ugate gradient method,a modified spectral conj ugate gradient method is proposed for the large-scale unconstrained optimization problem in the inverse problem.The algorithm is convergent under the Wolfe search-ing.Numerical experiments show that the proposed algorithm is effective and feasible in image restoration.关键词
