Fusion Of HWD And Non Negative Matrix Factorization For Video Watermarking
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 3
Abstract
In the era of high speed network and World Wide Web, data can be easily accessed in a number of ways to share among each other. This data can be manipulated without any quality loss. Threat of intellectual property rights becomes a crucial issue due to this. The security of these online assets can be obtained using different techniques like encryption, fingerprinting, watermarking. In this paper we propose watermarking algorithms for protecting digital contentslike images,audio,video. This algorithm uses a new family of perfect reconstruction, non-redundant, and multiresolution geometrical transforms using the wavelet transform in conjunction with modified versions of directional filter banks (DFB for decomposition of video frames into frequency bands. Low frequencybandisfactoredusingNonnegativematrix factorization for dimension reduction. This hybrid algorithm proposes a more robust technique for video watermarking with no perceptual quality loss of video
