Sequential order one negative exponential (SOONE) function is used.to measure the sparsity of a two-dimensional (2D) signal. A 2D gradient projection (GP) method is developed to solve the SOONE function.and thus the 2D-GP-SOONE algorithm is proposed. The algorithm can.solve the sparse recovery of 2D signals directly. Theoretical analysis.and simulation results show that the 2D-GP-SOONE algorithm has a.better performance compared with the 2D smoothed L0 algorithm..Simulation results also show that the proposed algorithm has a better.performance and requires less computation time than 2D iterative.adaptive approach.
