an_intellegent_audio_water_marking_based_on_dwt-s
DL : 0
All three, Discrete Wavelet Transform (DWT) - Singular Value Decomposition (SVD) and Adaptive Tabu Search (ATS) have been used as mathematical tools for embedding data into an audio signal. In this paper, we present a new robust audio watermarking scheme based on DWT-SVD and ATS. After applying the DWT to the cover audio signal, we map the DWT coefficients, and apply the SVD, we search for the optimal intensity of audio watermarking by using the ATS. Experimental results show that the watermarking method performs well in both security and robustness to many digital signals processing, such as filtering, cropping, mp3 and random noise.

奇异值分解用于英文文本检索,画出频率矩阵第一奇异值向量和第二奇异值向量的分布图- a fast retrieval algorithm for English texts is proposed. First of all, the English texts are mapped into frequency matrixes of order 26 and the dimensions of texts representation space are reduced through Singular Value Decomposition. Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters.

本文提出一种在原始视频DCT(离散余弦变换)与SVD(奇异值分解)域自适应嵌入水印的算法。算法首先将视频流分割成一个个场景,场景中的视频图像被变换到DCT-SVD域中,水印量化嵌入在最大奇异上,实现了水印盲检测。同时实验证明该算法在满足透明性要求下也满足一定的鲁棒性要求,能够抵抗低通滤波、中值滤波、椒盐噪声、高斯噪声、H.264压缩攻击以及统计攻击和帧剪切等攻击。-This paper presents an original video in the DCT (Discrete Cosine Transform) and SVD (singular value decomposition) algorithm for adaptive watermark embedding. Firstly, a video stream is divided into scenes, scenes of the video image is converted to the DCT-SVD domain, the watermark embedded in the largest singular quantification, the realization of the watermark signal. Furthermore, the experiments show that the algorithm meet the transparency requirements are met under certain robustness requirements, can resist the low-pass filtering, median filtering, salt and pepper noise, Gaussian noise, H.264 compression attacks and attacks and frame shear statistics attack.
