Inertial self‐adaptive algorithm for solving split feasible problems with applications to image restoration

Abstract: We introduce a new self-adaptive algorithm for applications to image restoration problems. In order to study an image restoration, we consider the algorithm that contains inertial effects and step sizes, which is independent from the norm of the bounded linear operator. With some control conditions, the strong convergence to the minimum norm solution of the algorithm is obtained. Convergence analysis of the proposed algorithm is also discussed. Moreover, numerical results of image restoration problems illustra… Show more

“…for all n ≥ 0, where {α n }, {β n }, {γ n } are sequences of real numbers in (0, 1). Let N = 2 12 and M = 2 11 be the size of signal. Suppose that there are m nonzero elements in the original signal, then generate the Gaussian matrix A by using randn(M, N ), σ = 0.1 and ζ = m. Choose x 0 = A t y as the initial point.…”

“…Many problems in various elds, such as image reconstruction [12,14,23] and signal processing [1,13,20,21,22,24], can be modeled as xed point problems. Numerous authors have presented various iterative approaches for xed point numerical approximation.…”

“…For instance, these problems are applicable to solving convex programming, the minimization problem, variational inequalities, and the split feasibility problem. As a result, some applications of such problems are able to be taken into consideration, such as machine learning, the signal recovery problem, the image restoration problem, sensor networks in computerized tomography and data compression, and intensity modulated radiation therapy treatment planning, see [1][2][3][4][5][6][7][8][9].…”
