AB  - The recent explosion in digital video storage and delivery has presented strong motivation for high
performance video compression solutions. Video compression takes the advent of spatial, temporal and
psycho-visual redundancies which can be compensated efficiently by transform, motion estimation and
quantization respectively. An efficient video compression technique must preserve the trade-off between
compression ratio and the quality of the video. The performance of existing image and video coding standards
generally degrade at low bit-rates because of the underlying block based Discrete Cosine Transform (DCT)
scheme. Over the past decade, the success of wavelets in solving many different problems has contributed to
its unprecedented popularity. A new representation of these 2D (Image) signals called as wavelet footprints
are the finite scale space vectors containing all the wavelet coefficients generated by particular polynomial
discontinuities. The objective of this study is to develop an efficient compression scheme for the video stream
by fast motion estimation algorithms up to half pixel accuracy as in newest international standard, ITU-T
H.264/AVC and to obtain better quality and higher compression ratio through wavelet footprints.
