چکیده
Image inpainting is the process of repairing damaged or missing areas an image by utilizing information from its surrounding environment. The fractional order operator, which processes details like textures and edges with a finer scale, has demonstrated better outcomes success in processing. This study draws inspiration definition singular integral Laplacian presents two adaptive variational functionals for inpainting, showcasing stable scheme. Moreover, numerical discretisation scheme used derived PDEs was constructed. proposed models can simultaneously restore missing, corrupted, undesirable regions while removing noise. Numerical experiments were conducted to test techniques, accompanied method comparisons.

Weighted Graph Laplacian and Image Inpainting
Abstract. Inspired by the graph Laplacian and the point integral method, we introduce a novel weighted graph Laplacian method to compute a smooth interpolation function on a point cloud in high dimensional space. The numerical results in semi-supervised learning and image inpainting show that the weighted graph Laplacian is a reliable and efficient interpolation method. In addition, it is easy ...
متن کاملInpainting - Based Image Compression
Inpainting-based image compression is an emerging paradigm for compressing visual data in a completely different way than popular transform-based methods such as JPEG. The underlying idea sounds very simple: One stores only a small, carefully selected subset of the data, which results in a substantial reduction of the file size. In the decoding phase, one interpolates the missing data by means ...
متن کاملSuper-resolution Based Image Inpainting
-This paper introduces a new examplar-based inpainting framework. A coarse version of the input image is first inpainted by a non-parametric patch sampling. Compared to existing approaches, some improvements have been done (e.g. filling order computation, combination of K nearest neighbours). The inpainted of a coarse version of the input image allows to reduce the computational complexity, to ...
متن کاملA Class of Fractional-Order Variational Image Inpainting Models
In this paper, we introduce fractional calculus into image inpainting and propose a new class of fractional-order variational image inpainting models, in both space and wavelet domains, inspired by the works of Bai and Feng. The corresponding Euler-Lagrange equations are given and proper numerical algorithm is analyzed. According to the simulations on several testing images, our algorithm demon...
متن کاملA Framelet-Based Approach for Image Inpainting
In this paper, we present an image inpainting algorithm based on framelet analysis. The motivation for using framelets is that the redundancy provided by the framelets makes it possible to propagate the accurate information from the vicinity of the region to be inpainted to the inside of the region to be inpainted. This is done by small perturbations of the framelet coefficients via thresholdin...
