Abstract
(English)
In this paper, we develop an efficient tree-model based compressed sensing (CS) algorithm.
Development of efficient algorithms for sparse signal reconstruction problem is an important research issue and various algorithms have been proposed.
Most of state-of-the-art CS algorithms assume only simple sparsity of the original signal.
But a realistic signal often has further structure in itself and it is known that it is possible to develop a CS algorithm with better performance by exploiting the signal structure.
Those algorithms are called model-based compressed sensing algorithm.
Model-based compressed sensing algorithms are less well studied.
We propose a tree-model based CS algorithm based on augmented Lagrangian method.
Numerical simulation show that the proposed algorithm is favorable for some cases.
