Abstract:
In [l], the use of McClellan transformations for the design of multidimensional filter banks from one-dimensional analysis/synthesis filters is presented for the case of is two-band, diamond-shaped pair. In [2], these concepts are expanded for the design of two-band filter banks with general parallelogram-shaped passband geometries. However, in [l, 21, the dlesign technique is restricted to filters which had zero-phase characteristics, which results in zero-phase two-dimensional filters. In this paper, we note that if the signal being processed is periodic, (which naturally arises when implementing filter banks in a size-limiting manner [a] for finite extent inputs), then the zero-phase restriction can be relaxed.read more

Adaptive McClellan transformations for quincunx filter banks
TL;DR: A particular two-parameter transformation function is developed that has sufficient flexibility to adapt its orientation in any direction and whose optimization involves a simple constrained least-squares problem in which the feasible set lies within a circle.

New subband decompositions and coders for image and video compression
TL;DR: It is revealed that if a two-band subband decomposition is performed (in the temporal dimension) of a progressively scanned video sequence, then notable gains can be achieved by encoding the high-temporal-frequency band using the directional sub band decompositions.

A 2-D FIR filter structure derived from the Chebyshev recursion
J. McClellan,D. Chan +1 more
TL;DR: In this paper, a new structure is proposed for the implementation of 2-D FIR digital filters designed by transformations of 1-D filters, which requires a minimum number of multiplications and uses directly as coefficients the impulse response samples of the original filter.

The directional filter bank: a multirate filter bank for the directional decomposition of images
TL;DR: A speaker grill, particularly applicable to speaker-type telephone sets and similar items, is composed of a plurality of closely spaced thin parallel ribs having a sinuous cross-section, for example somewhat Z-shaped, with a mask attached to the near face of the grill.

The time domain analysis and design of exactly reconstructing FIR analysis/synthesis filter banks
TL;DR: A time-domain framework is introduced for the analysis and design of general M-band analysis/synthesis filter banks and results in a set of time- domain conditions for reconstruction which can be used in a filter design procedure.
