低秩四元数矩阵分解模型的优化理论及其应用
Optimization Theory of Low Rank Quaternion Matrix Decomposition Model and Its Application
摘要
Abstract
This paper studies the low rank quaternion matrix decomposition model and its application in color image processing.Qua-ternion gradient descent algorithm and its improved version are proposed to solve the low rank quaternion matrix decomposition model.And the convergence of the algorithms is considered.Numerical results on color images show the feasibility and effective-ness of the proposed algorithms.关键词
