The main goal of this paper is to embed a watermark in the speech signal, using the three techniques such as Discrete Cosine Transform (DCT) along with Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT).In this paper, various combinations were tried for embedding the watermark image into the audio signal such as DWT and SVD, DCT with SVD and DCT, DWT with SVD. Their perform...

In their recent paper, Alnasser and Foroosh derive a wavelet-domain (in-band) method for phase-shifting of 2-D "nonseparable" Haar transform coefficients. Their approach is parametrical to the (a priori known) image translation. In this correspondence, we show that the utilized transform is in fact the separable Haar discrete wavelet transform (DWT). As such, wavelet-domain phase shifting can b...

Image decomposition based on the discrete wavelet transform (DWT) has been proposed for eecient storage and progressive transmission of images for visual browsing in digital image libraries. Although the compression aspects of the DWT have been carefully researched, reconstruction errors due to corrupted wavelet coeecients have received less attention. In this paper we consider the problem of b...

Since images will constitute a large part of future wireless data, we focus in this paper on developing energy efficient, computing efficient and adaptive image compression and communication techniques. Based on a popular image compression algorithm, namely, wavelet image compression. In this method I propose an implementation of discrete-time wavelet transform based image codec using Set Parti...

During their service life, marine pipelines continually accumulate damage as a result of the action of various environmental forces. Clearly, the development of robust techniques for early damage detection is very important to avoid the possible occurrence of a disastrous structural failure. Most of vibration-based damage detection methods require the modal properties that are obtained from mea...

Color image enhancement is a very important pre-processing stage in face detection and face recognition applications especially when the environment is very dark. In this paper, a color color image enhancement with the adaptive filter and discrete wavelet transform (DWT) is proposed. Discrete wavelet transform is used to improve image enhancement and stationary wavelet transform is used to redu...

speech compression is the digital signal which is compressed by using various techniques for transmission. This paper explains a transform methodology for compression of the speech signal. In this paper speech is compressed by discrete wavelet transform technique afterward compressed signal is again compressed by discrete cosine transform afterward compressed signal is decompressed by discrete ...

As we move in to the future there is a rising demand for high performance, high capacity and high bit rate wireless communication systems to integrate wide variety of communication services such as high-speed data, video and multimedia traffic as well as voice signals. Discrete wavelet transform (DWT) is faster than FFT hence it’s replaced by transform technique for OFDM. This project proposes ...

During the last few decades, there is the continuous development of networking across the globe which simplified their path in data communication, multimedia signal processing and so on. It also ensures there is an effective need of copyright protection in multimedia processing. These data are actually very easy to hack: information becomes vulnerable to interception, copying, tampering or corr...
