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.
