Joint Sparse Representation Model for Multi-Channel Image Based on Reduced Geometric Algebra
Sparse representations have been extended to color image processing. However, existing sparse models treat each color image pixel either as a scalar which loses color structures or as a quaternion vector matrix with high computational complexity. In this paper, we propose a novel sparse representati...
