Digital watermark is an effective way to protect the rightful ownership of multimedia contents. In this paper, a multi-watermarking scheme is proposed, in which three independent binary watermarks are embedded in a grayscale digital image. In order to embed multi-watermarks simultaneously to improve the quality of watermarked image and also robustness of extracted watermarks, the three 2-D watermarks...
In this paper, a novel copyright protection zero-watermarking scheme that combines the discrete wavelet transform (DWT) and the singular value decomposition (SVD) is proposed. Instead of modifying the original image data, which inevitably causes some permanent quality degradation, to embed a watermarking, the proposed scheme constructs a watermarking from the image features which extracts from the...
To protect the copyright of the digital image in the guarantee of image quality, a robust zero-watermarking scheme is proposed in the paper. The scheme selects the wavelet coefficients correctly to exploit the advantages of wavelet transform. Then the binary watermark is concealed into master share and ownership share by using the visual cryptography technique. Finally the ownership share is registered...
Effective prediction of the software reliability is one of the active pares of software engineering. This paper proposes a novel approach based on wavelet transform and neural network (NN). Using this approach, the time series of software faults can be decomposed into four components information, and then predict them by NN respectively. The experience results show that the performance of novel software...
