抄録(英) | This paper presents a method of copyright protection for digital still images based on their recognition with a large-scale image database. For the purpose of copyright protection of images, digital watermarking has been extensively studied for more than a decade. However, it is still difficult to achieve enough robustness against alternations such as StirMark attacks. In order to solve this problem, we propose a method of copyright protection based on new image recognition technologies that are tolerant to various image distortions including geometric transformations. The image recognition enables us to find a corresponding image from at least tens of thousands of reference images to be protected in response to a query image that undergoes StirMark attacks and digital watermarking. From experimental results using 10, 000 images in the database, we have confirmed that the method is capable of recognizing 99.5% of query images only within 216ms/query (excluding feature extraction). |
