% May 2010 % This matlab code implements TVL1 based Hybrid Compressive Sensing using LSQR. % Only suitable the small scale data due to the costly storage and computation. % % A - M x N measurement matrix: random sampling alone or hybrid sampling (random sampling and low resolution sampling) % % gamma - weight for L1-norm of the diagonal gradients % % tol - tolerance for stopping criterion. % - DEFAULT 1e-3 if omitted. % % maxIter - maximum number of iterations % - DEFAULT 50, if omitted. %Original TVL1 based Hybrid Compressive Sensing problem: % min ||gx ||_1 + ||gy ||_1 +\gamma *(||gxy ||_1 + ||gyx ||_1) % s.t. A*I = b and I >=0 %It can be solved using PDCO as follows % min c*x s.t. Phi * x =B % x = [I; gx; -gx; gy; -gy; gxy; -gxy; gyx; -gyx] % Phi and B enforce the measurement (A) and constrant among the elements of x; % Xianbiao Shu, May 2010.
