Abstract
This paper proposes inpainting technique based on space distance for scratched image which damage location is given. Conventional methods using pixel value can be categorized into two major classes. One is a pixel-based method which interpolates missing regions on a pixel-to-pixel basis by evaluating continuity of luminance. The other is a patch-based method which uses image fragment for interpolation based consistency between the missing region and source region. However, if scratch damages are widely and densely distributed on the image, both methods are inapplicable to it. In the context of it, the inpainting technique which considers space distance between the missing region and source region as a likelihood is proposed. By the reason that the proposed method is categorized into a pixel-based method, it is applicable to images which can not secure the image fragment required by patch-based method. In addition, interpolating without having to refer the pixel values of source region, it is also applicable to images which can not evaluate continuity of luminance. Since the interpolation pixels are determined by only it's location in missing region, the proposed method requires no iterative computation and the information of mid-flow, resulting in high-speed computing. The experiment shows performance of proposed method for variety of images.
