A subband decomposition using wavelet filters has become an effective basis for image compression. The use of a ladder structure for the subband filtering provides a fast implementation and allows the system to be useful at video rates. A system is p

A ladder implementation of a subband/vector quantization (VQ) coder is presented. The ladder realization significantly reduces the number of computations required to achieve the desired decomposition, compared to the separable system presented by R.E

Many video compression systems use motion-compensated prediction to take advantage of the temporal redundancy. Typically, the motion compensation is done on a block-by-block basis using a fixed block size. This paper examines methods to improve motio

Subband coding is becoming a viable compression method for video transmission, since the subband system can be efficiently split into a base layer and an enhancement layer without incurring any overhead. This is desirable in ATM and other packet netw

A subband decomposition using wavelet filters has become a popular and effective basis for image compression. The use of a ladder structure for the subband filtering provides a fast implementation, and allows the system to be useful at video rates. I

A polynomial representation using a set of generalized Lagrange polynomials for a basis is considered as an alternative to the natural representation. This new representation, which is employed in a previously described APL filter design package,8 is

A complete APL analogue filter synthesis package is described which includes provisions for avoiding ill-conditioning when polynomials with clustered roots are considered. The solution to the numerical problem that is employed in this package is the
