huffman algorithm and adaptive huffman algorithm binary image using matlab

Consider a black and white image. This image is made up of many pixels that are all different shades of gray which have a number value corresponding to the brightness or darkness of the shade. Black is 0, white is 255, and all the numbers in between are shades of gray. So, each pixel is coded as some integer from 0 to 255. In order to encode these integers, we must use bits. A bit have a value of either 0 or 1, and the maximum number of bits needed to code any number be ....etc

Image Steganography Technique Based on Wavelet Transform
In the technique of steganography, information is concealed in unremarkable cover media so as not to arouse an eavesdropper s suspicion. It is widely used in the field of information security. The strengths and counter measures are
driven by weaknesses and vulnerabilities. There are easy to use communication channels for steganography. In this article, a modified high-capacity image steganography technique that depends on wavelet transform is described which has acceptable leve ....etc

matlab code for speech recognition using wavelet transform

Speech Recognition Using Wavelet Transform is a good MATLAB based Electronics Project for Engineering Students and tells about the Speech Recognition. Spoken language is converted to text in Automatic speech recognition (ASR). Speech recognition is currently used in many real-time applications, such as cellular telephones, computers, and security systems. Speech recognizers consist of a feature extraction stage and a classification stage. You can also Subscribe to FINAL YEAR PROJECT'S ....etc

HIGH CAPACITY AND SECURITY STEGANOGRAPHY USING
DISCRETE WAVELET TRANSFORM



Abstract

The secure data transmission over internet is achieved using Steganography. In
this paper High Capacity and Security Steganography using Discrete wavelet
transform (HCSSD) is proposed. The wavelet coefficients of both the cover and
payload are fused into single image using embedding strength parameters alpha
and beta. The cover and payload are preprocessed to reduce the pixel range to
ensure the payload is recovered a ....etc
