Image Inpainting Using Texture Synthesis and Structure Propagation
S. Sharoon Shalini and D. Menaka
Abstract:
Inpainting is a technique which is to modify an image in an undetectable way. For image inpainting, an 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. The person or object to be inpainted is automatically replaced by data sampled from the remainder of the image. Applications of this technique include the restoration of old photographs and damaged film; removal of superimposed text like dates, subtitles, or publicity; and the removal of entire objects from the image like microphones or wires in special effects. In the past, this problem has been addressed by two classes of algorithms: (i) ?texture synthesis? algorithms for generating large image regions from sample textures, and (ii) ?inpainting? techniques for filling in small image gaps. The advantages of these two approaches are combined into a single efficient algorithm in exemplar based inpainting. For each pixel in the contour, a patch is built with a given size. Then, exemplar based algorithm is applied to find out the target patch that has the highest priority. After that a search is performed to find a patch in the source area that is the most similar to the target patch. Once the best-fit patch has been found, the color values from the source patch is copied to the target patch. Only those pixels in the target region will be filled. After filling the patch, the contour list is updated. Eventually, the whole target region will be entirely filled, and the contour list would be empty. At this point, inpainted image is obtained.
