The Research and Application of Digital Image Inpainting Based on Improved CDD model
نویسندگان
چکیده
This article studies a new image restoration model, by introducing the edge weighting function and improving the diffusion coefficient of the CDD (curvature-driven diffusions) model, to solve that the CDD model needs long time and has unnatural edge transitions. Empirical results show that the repairing time of the proposed model is less than the traditional model, the repaired image is clearer and the transition is more natural. Keywords-Digital Image Inpainting, Partial Differential Equation, CDD Model

Multigrid Method for a Modified Curvature Driven Diffusion Model for Image Inpainting
Digital inpainting is a fundamental problem in image processing and many variational models for this problem have appeared recently in the literature. Among them are the very successfully Total Variation (TV) model [11] designed for local inpainting and its improved version for large scale inpainting: the Curvature-Driven Diffusion (CDD) model [10]. For the above two models, their associated Eu...

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
متن کاملImage Inpainting by using CDD Model for Image Restoration
AbstractImage inpainting or image retouching is the method of filling in or repairing the missing area of an image from the nearby pixels information by some algorithm. Its goal is to recover images with limited data loss and tries to obtain outputs of damaged area of an image in such a way that the recovered images look identical to original image. In our proposed method we will divide the dam...
متن کاملMathematical Models for Local Nontexture Inpaintings
Abstract. Inspired by the recent work of Bertalmio et al. on digital inpaintings [SIGGRAPH 2000], we develop general mathematical models for local inpaintings of nontexture images. On smooth regions, inpaintings are connected to the harmonic and biharmonic extensions, and inpainting orders are analyzed. For inpaintings involving the recovery of edges, we study a variational model that is closel...
متن کاملCorrelated discrete data generation using adversarial training
Generative Adversarial Networks (GAN) have shown great promise in tasks like synthetic image generation, image inpainting, style transfer, and anomaly detection. However, generating discrete data is a challenge. This work presents an adversarial training based correlated discrete data (CDD) generation model. It also details an approach for conditional CDD generation. The results of our approach...
