A Wavelet-Based Digital Watermarking for Video
— A novel video watermarking system operating in the three-dimensional wavelet transform is here presented. Specifically the video sequence is partitioned into spatio-temporal units and the single shots are projected onto the 3D wavelet domain. First a gray-scale watermark image is decomposed into a series of bitplanes that are preprocessed with a random location matrix. After that the preproce...
متن کاملStructural Damage Detection Using Digital Video Imaging and Wavelet Transformation
Non-contact measurement offers convenient and less expensive setup. Sometimes, they may also be the only resort because the structure is too small to be instrumented with contact sensors and/or the additional mass of the sensor is too large to use. In other cases, the structure is inaccessible due to obstruction for the case of tall/large structures such as bridges or towers. The digital imagin...
متن کاملA Wavelet-Based Watermarking for Digital Images and Video
Recently, digital contents are copied easily because of the development of digital technology. So digital watermark technique which aims at copyright protection of digital contents becomes more and more important, and various watermarking methods have been proposed. In this paper, we proposed a method of digital watermark for still image by using wavelet packets, and examine the robustness of t...

متن کاملDigital watermarking using multiresolution wavelet decomposition
We present a novel technique for the digital watermarking of still images based on the concept of multiresolution wavelet fusion. The algorithm is robust to a variety of signal distortions. The original unmarked image is not required for watermark extraction. We provide analysis to describe the behaviour of the method for varying system parameter values. We compare our approach with another tra...
