Graph Regularized Non-negative Reduced Biquaternion Matrix Factorization for Color Image Recognition 事件

Graph Regularized Non-negative Reduced Biquaternion Matrix Factorization for Color Image Recognition arXiv:2606.03654v1 Announce Type: new Abstract: Non-negative reduced biquaternion matrix factorization (NRBMF) uses the product of reduced biquaternion (RB) matrices to incorporate the non-negativity constraints of color image pixels into the factorization process. However, NRBMF mainly focuses on reconstruction accuracy and does not exploit the local geometric structure of image data, which may
