encrypted domain, H.264/AVC, codeword substituting. I. INTRODUCTION H .264/AVC [1] video coding standard has been developed and standardized collaboratively by both the ITUT VCEG and ISO/IEC MPEG organization. H.264/AVC is a video compression format [2] i.e. standard for high definition digital video. H.264/AVC video streams generally avoids leakage of video content which can help to address the security and privacy concerns with cloud computing. Similarly when medical videos or surveillance

Abstract— This paper presents the design of an optimized Compressive Sensing (CS) based image compression technique for data transmission over mobile wireless noisy channel. The proposed technique is more robust to channel noise. It uses individual measurement driven coding scheme, which facilitates simpler encoder design. The shift of computational burden from encoder to decoder is more suitable for mobile devices applications where computational power and battery life are limited. This paper also

tremendous measure of memory, the main concept for the speech compression algorithm is presented here, in which bit rate of the speech signal is reduced with maintaining signal quality for storage, memory saving or transmission over the long distance. The concentration of this project is to compact the digital speech signal using Discrete Wavelet Transform and reconstruct same signal using inverse transform, in .NET. The algorithm of Compression is oriented in three basic operation, they are apply the

I4 Day Concrete Test Introduction and Objective In civil engineering construction, one of the most determining factors for the stability of a structure is the maximum strength attained by concrete after 14 and 28 days. As such, it is often critical for an engineer to test a particular test concrete cylinder mix for the ultimate compressive strength and then compare it with the design strength before allowing the concrete mix to be replicated in large quantities. The factors that affect the ultimate

A Wireless Sensor Network can be composed of large number of tiny of sensor nodes spread in a wide area and communicating with each other either directly or through routing mechanisms to the other nodes. One or more of the nodes are the base station with uninterrupted battery source than the other nodes. Since the devices in WSN are often tiny devices with small form factor the computational power of these devices is usually small because there will not support large amount of hardware. Furthermore

A bitrate is a term widely used in audio compression” (“MP3 Info”). It is the

usually use for photos that you have taken on a digital camera which are for example JPEG files(13). Lossless Lossless is a type of compression, when the file is compressed the quality still stays the same when the file is reloaded and all the information will be restored completely. This method of compressing files can be applied to image and text. This method of compression is mostly used for text and

INTRODUCTION Some people suffer severe motor impairments cannot express their thoughts as healthy for assistance of patients and can be controlled by user alone. It uses EEG signals as input and produces output signals in the form of inverse DWT. Communication system between human brain and computer is called BCI. This enables generation of control signals from brain signals, such as sensory motor rhythms and evoked potentials, therefore persons, because they are not capable

J. Dai, Oscar C. A., C. Pang, W. Yang and F. Zou [4] proposed technique of film grain noise which is inherent in analog film stock and is generated in the process of exposing and developing silver-halide crystals. Film grain noise can be modeled as a zero-mean Gaussian noise and the noise variance varies with the intensity of noise-free signal. Film grain noise is temporally independent. Film grain noise is spatially correlated. The higher the image resolution is, the more likely that the viewer

Image Steganography: In today’s digital world secret messages get embedded in to the digital image which is called as Image Steganography where cover object used is Image . Because of the limited power of the Human vision system this method is most commonly used [5]. According to Duncan Sellars [4], image can be explains as “ To a computer , an image is an array of numbers that represents light intensities at various points or pixels. These pixels make up the images raster data. Image steganography
