| Abstract: | A new algorithm for embedding and extracting watermark in the domain of middle frequency of the carrier im-ages is presented which is based on non-uniform B-spline wavelet transformation. Using the algorithm binary watermark image of any shapecan be embedded into thecarrierimage, and canbeextracted blindly. Examples show thatthealgorithm is robust against common attacks. |
