Image Restoration based on A Hybrid Model by Alternating Direction Optimization
نویسندگان
چکیده
In order to better preserve the edge features and also refrain them from the staircasing effect in smooth regions, this paper investigates a hybrid model for restoring the blurred images with additive Gaussian noise and an effective iterative scheme based on alternating direction method is employed to solve the minimization problem suggested by us with two regularization terms. Numerical experiments demonstrate that the hybrid scheme proposed by us is superior to the model with only one regularization term in respect of image restoration quality.

Frame-based Poisson image restoration using a proximal linearized alternating direction method
The restoration problem for Poissonian images, arising in medical and astronomical applications, is an active research area. The associated optimization models are quite challenging since the fidelity term of the problem is not a quadratic function and the regularizer is usually nonsmooth. Recently, the augmented Lagrangian-based alternating direction method has been proposed to solve the total...
متن کاملEffective Alternating Direction Optimization Methods for Sparsity-Constrained Blind Image Deblurring
Single-image blind deblurring for imaging sensors in the Internet of Things (IoT) is a challenging ill-conditioned inverse problem, which requires regularization techniques to stabilize the image restoration process. The purpose is to recover the underlying blur kernel and latent sharp image from only one blurred image. Under many degraded imaging conditions, the blur kernel could be considered...

In this paper, we study alternating direction methods for solving constrained total-variation image restoration and reconstruction problems. Alternating direction methods can be implementable variants of the classical augmented Lagrangian method for optimization problems with separable structures and linear constraints. The proposed framework allows us to solve problems of image restoration, im...
متن کاملImage Restoration by Variable Splitting based on Total Variant Regularizer
The aim of image restoration is to obtain a higher quality desired image from a degraded image. In this strategy, an image inpainting method fills the degraded or lost area of the image by appropriate information. This is performed in such a way so that the obtained image is undistinguishable for a casual person who is unfamiliar with the original image. In this paper, different images are degr...
متن کاملDouble regularization medical CT image blind restoration reconstruction based on proximal alternating direction method of multipliers
To solve the problem of CT image degradation, a double regularization CT image blind restoration reconstruction method was proposed. The objective function including both a clear image and point spread function was established. To avoid the over-smoothing phenomenon and protect the detail, the objective function includes two constraint regularization terms. They are total variation (TV) and wav...
