Feature Based Affine Invariant Watermarking Robust to Geometric Distortions
碩士 === 朝陽科技大學 === 資訊管理系碩士班 === 95 === This work, proposes a robust digital watermarking scheme based on feature points as a defense against illegal user attacks, such as, rotating, scaling and translation. First of all, a Gaussian filter is first adopted to discovery the invariant feature points. Th...
