Analysis of Video Compression Algorithms Using DCT, DWT and FFT

Abstract

Compression creates a brand new document that shops records in a format that require much less area. Compression strategies are used in video conferencing, video telephony, video on mobile telephone, video on internet. The compression of an picture or video record is of splendid concern in virtual communication machine due to the storing capacities and constraints in the transmission rate. And a video compression format or a video compression specification is a specification for digitally representation of video as a file or a piece circulate. Amongst them, this system used the avi format for video file compression. In this system, the avi format video is compressed by using discrete cosine transform (DCT), discrete wavelet transform (DWT) and fast fourier transform (FFT). And then, this system analyze the performance of each compression techniques according to the compression ratio.
