International Journal of Computer Applications (0975 – 8887) Volume 115 – No. 17, April 2015 20 An Enhanced Technique for Exemplar based Image Inpainting Jaspreet Kaur Chhabra Department of Computer Science & Engg S.V.C.E Indore, M.P, India Vijay Birchha Department of Computer Science & Engg S.V.C.E Indore, M.P, India ABSTRACT Image inpainting is an emerging area of image processing; with the help of this we can fill the misplaced or lost regions of a given image. In real life for example in the museum world the job of inpainting of precious images or paintings is fulfilled with the help of an expert of arts. Like this in the digital world the job of image inpainting is fulfilled with the help of inpainting algorithms. Various algorithms have presented in the past to achieve the task of image inpainting. In this paper, we have suggested a novel exemplar based image inpainting technique. The suggested technique will remove whole object from a given image or a portion of the object & it will offer high quality outcomes. Keywords Image Inpainting, Exemplar Based Image Inpainting, Object Removal, and Filling Area. 1. INTRODUCTION Recently, image inpainting techniques have achieved high reputation in the area of digital image processing. The techniques that are utilized for repairing the lost part of a picture or image are known as image inpainting technique. The application area of image inpainting techniques is very large; these techniques are utilized for- elimination of any object or anything from a given image, reinstallation of longstanding pictures/images, deletion of blurs of dust in picture/image, improvement of red-eye, inventive effect by deleting objects etc. Generally, we have seen two categories of procedures in literature that deal with the problems related to image inpainting and which are described above and those procedures are based on- texture synthesis and image inpainting. The procedures which are utilized to produce large scale image regions with the help of sample textures are called texture synthesis methods, these types of methods mainly concentrated on texture part of image. The procedures which are utilized to fill up the little gap in image are called inpainting methods, these types of methods mainly concentrated on structural part of picture/image [1][3]. A new type of image inpainting method recognized as exemplar based image inpainting method have proposed in literature, which employ both texture synthesis technique as well as inpainting technique. So, we can recreate both part of an image texture part and also structural part with the help of exemplar based image inpainting technique [2][3]. In literature we have studied various types of image inpainting approaches, for example- PDE based image inpainting approaches, Exemplar based image inpainting techniques, Texture Synthesis based image inpainting methods, Semi- automatic & Fast Inpainting methods and Hybrid inpainting methods. Figure 1: Example of Image Inpainting Figure-1 shows the example of image inpainting, in which the picture is divided into three parts. The first part shows the original picture, from which we want to remove the photo of man and restore the picture without man. The intermediate part shows the picture without man but with some distortion. Part three shows that the final required picture without man and without distortion. Here, part two and three required image inpainting. The exemplar based image inpainting technique efficiently recreates an image with large object or target regions. There are two steps which are utilized by exemplar based image inpainting technique- at first the priority assignment is prepared and second select the best matching patch from image [3]. The exemplar based image inpainting technique choose the most similar patches from the area of image to be inpaint, then the matching of these most similar patches is computed by certain metrics, and finally the missing area is fill up by most similar patches. On the basis of filling order, this method fill up the structures in the absent regions by utilizing the spatial information/ details of nearby regions [1] [4]. In this paper, we have suggested a novel exemplar based image inpainting technique. The suggested technique will remove whole object from a given image or a portion of the object & it will offer high quality outcomes. 2.
