信息内容 weightedstructural 相似性度量 （IW 独） 是 structuralsimilarity （独） 索引扩展纳入信息 contentweighted 池的想法。同样的想法，也可以适用峰值信号-到-noiseratio （PSNR），从而导致信息内容加权峰值信噪比 （IW PSNR）。在以下文件中提供了详细信息：-周王和李强，"信息内容权数为感性形象 QualityAssessment，"汇刊图像加工，第 20 卷，第 5，pp.1185–1198，2011 年 5 月。

采用CG法求解稀疏对称奇异矩阵得到的Ax=b(Implementation of a conjugate-gradient type method for solving sparse linear equations: Solve Ax = b or (A- sI)x = b. The matrix A- sI must be symmetric but it may be definite or indefinite or singular. The scalar s is a shifting parameter – it may be any number. The method is based on Lanczos tridiagonalization. You may provide a preconditioner, but it must be positive definite. )
