| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents a discrete optimization problem-based removal of show-through tequnique. In scanning duplex printed documents, show-through may degrate the image quality and character recognition rate. Show-through is a common phenomenon where the texts or figures on one side is appered on the other side. There are two methods to remove show-throught. One is using one-side document, and other is using both-sizes. Latter methods, its precision depend on alignment of documents, and if either side doesn't exist, we cannot use its method. Former methods, we can consider estimating both-sides intensity of each pixels in documents by using discrete optimization problem, it is difficult applying to high resolution documents because of its number of label is 256 x 256. In this report, we propose decreasing number of label three, by estimating pixel's component(forground, show-through or background pixel). By this method, we confirmed that removing show-throught faster. |
