| Description |
LpAnanlysis
Algorithm for solving problems of the form:
min ||Ax||_p s.t. ||y-Hx||_2 < err
LpSynthesis
Algorithm for solving problems of the form:
min ||x||_p s.t. ||y-Hx||_2 < err
LpplusTV
min ||x||_p + TVlambda*TV(A'x) s.t. ||y-Hx||_2 < err
All of them are efficient first-order algorithms. They do not have restrictions on the operators H or A. |
