Detailed Survey on Exemplar Based Image Inpainting Techniques
2014
Image inpainting is a technique which is used to patch up the missing area in an image. In early years image inpainting techniques gained the high popularity in the field of image processing, used for restoration of damaged images. The aim of image inpainting is to fill in the missing area in an image which is visible to human eyes. Image inpainting is also applied for reinstallation of old images/films, correction of red-eye, object elimination in digital photographs, removal of spots of dust in image/film, creative effect by removing objects etc. There are different types of image inpainting techniques such asexemplar based image inpainting, texture synthesis based image inpainting, PDE based image inpainting, hybrid inpainting and Semi-automatic and Fast Inpainting. In this paper we provide a detailed survey on Exemplar based image inpainting. Keywords-Inpainting, Exemplar Based Inpainting, PDE Based Inpainting, Texture Synthesis, Hybrid Inpainting, Object Removal, Filling Area.
Image Inpainting is the art of filling in missing data in an image. The purpose of inpainting is to reconstruct missing regions in a visually plausible manner so that it seems reasonable to the human eye. There have been several approaches proposed for the same. In this paper, we present an algorithm that improves and extends a previously proposed algorithm and provides faster inpainting. Using our approach, one can inpaint large regions (e.g. remove an object etc.) as well as recover small portions (e.g. restore a photograph by removing cracks etc.). The inpainting is based on the exemplar based approach. The basic idea behind this approach is to find examples (i.e. patches) from the image and replace the lost data with it. This technique can be used in restoring old photographs or damaged film. It can also remove superimposed text like dates, subtitles etc.; or even entire objects from the image like microphones or wires to produce special effects. We obtained good quality results quickly using our approach.
A Comparative Analysis of Exemplar Based Image Inpainting Algorithms
European Journal of Scientific …, 2011
Image inpainting refers to the task of filling in the missing or damaged regions of an image in an undetectable manner. Many researchers have proposed a large variety of exemplar based image inpainting algorithms to restore the structure and texture of damaged images. However no recent study has been undertaken for a comparative evaluation of these algorithms. In this paper, we are comparing various exemplar based image inpainting algorithms which do not have diffusion related blur in the result image. The analyzed algorithms are Antonio Criminisi et al's Region filling algorithm, Jiying Wu et al's Hybrid algorithm and Zhaolin Lu et al's Image completion algorithm. Both theoretical analysis and experiments have made to analyze the results of these exemplar based image inpainting algorithms on the basis of Peak Signal to Noise Ratio (PSNR).
Analysis of Exemplar Based Image Inpainting
Image Inpainting is an art of modifying the digital image in such a way that the modifications /alterations are undetectable to an observer who has no idea about the original image. Image Inpainting is technique in which it mainly used to filling the region which are damaged and want to recover from unwanted object by collecting the information from the neighboring pixels. In this paper here they provide an analysis of different Exemplar based techniques used for image Inpainting. This proposed work presents a brief comparative study of different Exemplar based image Inpainting techniques.
Survey on Image Inpainting Techniques: Texture Synthesis, Convolution and Exemplar Based Algorithms
Image Inpainting is the art of filling in missing data in an image. The purpose of inpainting is to reconstruct missing regions in a visually plausible manner so that it seems reasonable to the human eye. There have been several approaches proposed for the same. The objective of this paper is to review three such methods – Texture synthesis, Convolution and Exemplar based Algorithm. Texture synthesis can be used to fill in holes in images, create large non-repetitive background images and expand small pictures. Convolution based image inpainting algorithms are very rapid, however in many cases; they don't provide adequate results in sharp details such as edges. Exemplar-based methods provide impressive results in recovering textures and repetitive structures. However, their ability to recreate the geometry without any example is limited and not well understood. This paper summarizes the combination of these algorithms and proposes a new Hybrid Inpainting Algorithm for inpainting large as well as small regions in less time. Future aspects of the study are also discussed.

Inpainting, the technique of transform an image in an imperceptible form, is as past as art itself. The main objective of inpainting is from the reinstallation of damaged paintings and photographs to the elimination of chosen objects. Image Inpainting is used to filling the misplaced or smashed region in an image make use of spatial information of its neighbouring region. Inpainting algorithm have numerous applications. It is attentively used for restoration of older films and object removal in digital photographs. It is also useful to red-eye correction, compression etc. The objective of the Inpainting is to change the damaged region in an image in which the inpainted region is invisible to the common observers who are not familiar with the original image. There have been quite a few approaches are proposed for the image inpainting techniques. This proposed work presents a brief survey of different image inpainting techniques and relative study of these techniques. In this paper provide an analysis of different techniques used for image Inpainting. Finally a best inpainting technique is suggested in this paper.
Structure and texture image inpainting
2010
Inpainting refers to the task of filling in the missing or damaged regions of an image in an undetectable manner. We have an image to be reconstructed in a userdefined region. We use a fast decomposition method to obtain two components of the image, namely structure and texture. Reconstruction of each component is performed separately. The missing information in the structure component is reconstructed using a structure inpainting algorithm, while the texture component is repaired by a texture synthesis technique. To obtain the inpainted image, the two reconstructed components are composed together. Taking advantage of both the structure inpainting methods and texture synthesis techniques, we designed an effective image reconstruction method. Comparative reconstructed test images show the merits of our proposed approach in providing high quality inpainted images.

Even though fabulous development happens in image process province, still "filling the missing spaces" is area of concern in it. Although mass of progress has been created within the past years, still lot effort to be done. A distinctive algorithmic rule is given for examplarbased inpainting. within the estimated algorithmic rule inpainting is applied on the coarse version of the input image, latter stratified primarily based super resolution algorithmic rule is employed to seek out the data on the missing areas. The distinctive issue of the projected technique is less complicated to inpaint low resolution than its counter half. To create inpainting image less sensitive to the parameter projected examplar-based patch propagation algorithmic rule on a spread of natural pictures. We tend to apply our algorithmic rule to the applications of text removal, object removal and block completion. We tend to compare our algorithmic rule with the previous diffusion-based, examplar-based, and sparsity-based inpainting algorithms.
