Wavelets are mathematical functions. The wavelet transform is a tool that cuts up data, functions or operators into different frequency components and then studies each component with a resolution matched to its scale. It is needed, because analyzing

Matlab Steganography Example using Wavelet Transform. Hiding Data inside an Image using 2-D Haar Wavelet Transform in Matlab. Complete Encoding and Decoding example. [email protected] description

In this paper, EEG signals are the signatures of neural activities. There have been many algorithms developed so far for processing EEG signals. The analysis of brain waves plays an important role in diagnosis of different brain disorders. Brain is m

In recent world video and image compression, enhancement, restoration have become very essential. There are many applications where we need to use different transform techniques to convert the signal or data in frequency or time domain. However, with

Several developments in the transfer of data through the internet make it easier to transfer the data faster and accurately to the destination. But in this, anyone can misuse and modify the critical information through hacking. Video steganography is

Content based indexing methods are of great interest for image and video retrieval in audio visual archives, such as in the DiVAN project that we are currently developing. Detecting and recognizing human faces automatically in video data provide user

An interpolation based method, such as bilinear, bicubic, or nearest neighbor interpolation, is regarded as a simple way to increase the spatial resolution for the LR image. It uses the interpolation kernel to predict the missing pixel values, which

Thesis Report on image steganography using wavelet transformFull description

Now a day, in the era of technology every media is converted into digital media or objects. This digital media is transfer from one place to another place by using the internet for different purposes. The size of these digital media is play major rol

Speech signal can be compressed and decompressed by discrete wavelet transform technique. Discrete wavelet transform compression is based on compressing speech signal by removing redundancies present in it. Speech compression is a technique to transf
