A new algorithm is proposed for removing large objects from digital images. The challenge is to fill in the hole that is left behind in a visually plausible way. In the past, this problem has been addressed by two classes of algorithms: 1) "texture synthesis" algorithms for generating large image regions from sample textures and 2) "inpainting" techniques for filling in small image gaps. The former has been demonstrated for "textures"-repeating two-dimensional patterns with some stochasticity…

Inpainting means filling of areas/regions of an image or video in such a way that the modified region(s) is visually agreeable to human eye and Restoration of a damaged/historical image has always been an important part of image processing.

Simultaneous structure and texture image inpainting

The novel contribution of the paper is the combination of these three previously developed components: image decomposition with inpainting and texture synthesis, which permits the simultaneous use of filling-in algorithms that are suited for different image characteristics.

Image replacement through texture synthesis

This work proposes a technique based on Heeger and Bergen's texture synthesis algorithm (1995), which can be substituted with a synthetic texture derived from another portion of the image by integrating a composition step into the aforementioned algorithm.

A variational model for filling-in gray level and color images

A variational approach for filling-in regions of missing data in gray-level and color images is introduced, based on joint interpolation of the image gray-levels and gradient/isophores directions, smoothly extending in an automatic fashion the isophote lines into the holes ofMissing data.

Synthesizing natural textures

The algorithm is extended to allow direct user input for interactive control over the texture synthesis process, which allows the user to indicate large-scale properties of the texture appearance using a standard painting-style interface, and to choose among various candidate textures the algorithm can create by performing different number of iterations.

Fragment-based image completion

A new method for completing missing parts caused by the removal of foreground or background elements from an image, iteratively approximating the unknown regions and composites adaptive image fragments into the image to synthesize a complete, visually plausible and coherent image.

Image analogies

This paper describes a new framework for processing images by example, called “image analogies,” based on a simple multi-scale autoregression, inspired primarily by recent results in texture synthesis.

A Non-Hierarchical Procedure for Re-Synthesis of Complex Textures

It is shown that the accurate reproduction of features in the input texture depends on the order in which pixels are added to the output image, which is capable of reproducing large features even if only the interactions of nearby pixels are considered.

Computational models for texture analysis and texture synthesis

Although the success of texture synthesis is highly dependent on the texture itself and the modeling method chosen, general conclusions regarding the performance of various techniques are given.
