Abstract: To solve the problem of lost information of scanned core image, an inpainting algorithm based on total variation model was presented. Using the information of the reference pixels in the neighborhood area of the inpainted area, the information was diffused to the inpainted area. The neighborhood relativity coefficient was introduced weighing the influence on target pixel point by inpainting neighborhood boundary. The experimental results show that the new method improves the inpainting effect, and is effective for core image inpainting.
