[image fusion] sparse representation multispectral image fusion matlab source code

1, Introduction to sparse representation Sparse representation theory Sparse representation uses a linear combination of fewer basic signals to express most or all of the original signals. After sparse representation, the more sparse the signal, the higher the accuracy of the reconstructed signal. Let x ∈ Rn be the signal to be processed, ...
