Blind restoration for nonuniform aerial images using nonlocal Retinex model and shearlet-based higher-order regularization
Aerial images are often degraded by space-varying motion blur and simultaneous uneven illumination. To recover high-quality aerial image from its non-uniform version, we propose a novel patch-wise restoration approach based on a key observation that the degree of blurring is inevitably affected by the illuminated conditions. A nonlocal Retinex model is developed to accurately estimate the refle...
متن کاملCompressive Sensing of Color Images Using Nonlocal Higher Order Dictionary
This paper addresses an ill-posed problem of recovering a color image from its compressively sensed measurement data. Differently from the typical 1D vector-based approach of the state-of-the-art methods, we exploit the nonlocal similarities inherently existing in images by treating each patch of a color image as a 3D tensor consisting of not only horizontal and vertical but also spectral dimen...
متن کاملAn Adaptive Strategy for the Restoration of Textured Images using Fractional Order Regularization
Total variation regularization has good performance in noise removal and edge preservation but lacks in texture restoration. Here we present a texturepreserving strategy to restore images contaminated by blur and noise. According to a texture detection strategy, we apply spatially adaptive fractional order diffusion. A fast algorithm based on the half-quadratic technique is used to minimize the...
متن کاملIterative Nonlocal Total Variation Regularization Method for Image Restoration
In this paper, a Bregman iteration based total variation image restoration algorithm is proposed. Based on the Bregman iteration, the algorithm splits the original total variation problem into sub-problems that are easy to solve. Moreover, non-local regularization is introduced into the proposed algorithm, and a method to choose the non-local filter parameter locally and adaptively is proposed....
متن کاملImage Restoration using Higher Order Statistics
Most of the techniques for image restoration are based on some known degradation models. But in many situations it is difficult to accurately measure the degradation factors or noise type that is the real motivation behind the use of blind deconvolution technique for image restoration. Here the observed degraded image is restored without having any prior knowledge about the noise type. Most of ...
