"traditional methods blur/ distort... Chaotic Mapping-based Sparse Representation overcomes noise/ computational complexity...  integrates into dictionary sequence, solving process of K-singular value decomposition dictionary update algorithm balancing traversal... simplifies search global optimal solutions, enhancing noise robustness... orthogonal matching pursuit greedy algorithm converges faster, complementing K-SVD, constructing high-resolution... reduced SR reconstruction complexity"
