compressive sensing, compressed sensing, sparse representation

Compressive Sensing: The Big Picture
Nuit Blanche's blog 
Compressive Sensing Resources, with plenty of software.

To summarize, if you acquire a signal in some basis that is incoherent with the basis in which you know the signal to be sparse in, it is very likely you will be able to reconstruct the signal from these incoherent projections.

l1_ls:
tau ( l1_ls 中的 lambda )的选择问题，tau >= tau_max = 10^-4 * norm(A^T y, inf)
lambda >= lambda2* 10^-4 * norm(A^T y, inf)
具体多大还是要看具体问题，有些比如 0.1* tau_max
