A Robust Image Authentication Method Based on Wavelet Transform and Teager Energy Operator
A novel digital watermarking for image authentication is proposed in this paper. Most previous proposed watermarking algorithms embed sequences of random numbers as watermarks. Here images are taken as watermarks for embedding. In the proposed approach, the host image is decomposed into wavelet coefficients. Local entropies of wavelet coefficients in the low-frequency subband are calculated by ...
متن کاملRobust voice activity detection using perceptual wavelet-packet transform and Teager energy operator
In this letter, a robust voice activity detection (VAD) algorithm is presented. This proposed VAD algorithm makes use of the perceptual wavelet-packet transform and the Teager energy operator to compute a robust parameter called voice activity shape for VAD. The main advantage of this algorithm is that the preset threshold values or a priori knowledge of the SNR usually needed in conventional V...
متن کاملVoice Activity Detection Based on Auto-Correlation Function Using Wavelet Transform and Teager Energy Operator
In this paper, a new robust wavelet-based voice activity detection (VAD) algorithm derived from the discrete wavelet transform (DWT) and Teager energy operation (TEO) processing is presented. We decompose the speech signal into four subbands by using the DWT. By means of the multi-resolution analysis property of the DWT, the voiced, unvoiced, and transient components of speech can be distinctly...
متن کاملAn Improved Speech Enhancement Method based on Teager Energy Operator and Perceptual Wavelet Packet Decomposition
According to the distribution characteristic of noise and clean speech signal in the frequency domain, a new speech enhancement method based on teager energy operator (TEO) and perceptual wavelet packet decomposition (PWPD) is proposed. Firstly, a modified Mask construction method is made to protect the acoustic cues at the low frequencies. Then a level-dependent parameter is introduced to furt...
متن کاملImage Denoising Using Bayes Shrink Method Based On Wavelet Transform
In this paper, a denoising method is presented for noise reduction in Ultrasound (US) images. This paper proposes an efficient method based on linear filtering for images which is corrupted due to Gaussian noise. The method consists in linear filtering of proper wavelet coefficients of the image, corresponding to diagonal and vertical details. The proposed denoising method has good performance ...
