communication application for discrete wavelet transform in matlab

Solution

The discrete wavelet transform is used in signal processing applications, such as video compression, internet communication compression, object recognition and numerical analysis.

Data compression is done using DWT. Image compression, Image reconstruction, analysing signals, compression of audio data, cognitive radio applications are main applications of discrete wavelet transform.

Image is filtered bylow pass and high pass filter. Image is decomposed into multi level which include approximation details, horizontal details, vertical and diagonal details.

Practical application are found in signal processing of accelerations for image recognition, image retrieval systems in digital communications.
