Performance evaluation of L1, L2 and SL0 on compressive sensing based on stochastic estimation technique Ha, Pham Hong; Vorapoj Patanavijit (2010-05)
In this paper, we proposed 2 algorithms based on L1 and L2 norm estimator to recover the signal by using just few components. Moreover we comprehensively present the recovery algorithm based on L1, L2 and SL0 for digital signal or image under some several noise models from their incomplete observation. The proposed algorithm is used with a matrix that the number of row is much fewer than the column. The algorithm states that if signal or image is sufficient sparse, we can recover it from small number of linear measurement by solving convex ...
