WANG Xiang-ling;ZUO Shuang-yong;ZHU Zhi-bin;Primary Education College,Yichun Early Childhood Teachers College;Department of Mathematics and Computational Science,Guilin University of Electronic Technology;  
A new conjugate projection gradient filter algorithm is established by modifying the search direction.In this algorithm,conjugate projection gradient technology and filter method are combined.By the introduction of the filter,this algorithm does not need to solve a QP sub-problem.With the idea of the conjugate projection gradient,this method is effective to avoid the restoration algorithm in general filter algorithms.Under some conditions,its global convergence is obtained.
