分块NMF及其在图像压缩中的应用

1、    分块nmf及其在图像压缩中的应用    陈剑军摘 要 基于矩阵乃“局部构成整体”的思想和并行计算的模式，将矩阵分块进行非负矩阵分解，并将其用于图像压缩。实验表明：该方法可减少存储量、计算量，计算量的减少较为显著。关键词 矩阵分块 矩阵hadamard乘积 nmf 图像压缩：tn911.73 ：a doi：10.16400/ki.kjdkx.2016.09.066abstract based on the idea of "local integral whole" and the parallel computing mode

2、l， the matrix is divided into non negative matrix factorization， and it is used for image compression. experimental results show that this method can reduce the amount of storage and computation， and the computation is more significant.key words matrix block； matrix； hadamard product； nmf； image com
