Adaptive pre-filtering techniques for colour image analysis [PDF]

, 2007
One important step in the process of colour image segmentation is to reduce the errors caused by image noise and local colour inhomogeneities. This can be achieved by filtering the data with a smoothing operator that eliminates the noise and the ...

Adaptive equalisation in oversampled subbands [PDF]

, 1998
The potential presence of fractional delays, non-minimum phase parts, and a colouring of the channel output can require adaptive equalizers to adapt very long filters, which can have slow convergence for LMS-type adaptive algorithms.

Efficient Subband Adaptive Filtering with Oversampled GDFT Filter Banks

, 1997
This paper addresses the numerical efficiency of adaptive filtering implemented in subbands. Our approach first focuses on oversampled GDFT filter banks and their potential benefits over other possible subband decompositions.

On Implementation and Design of Filter Banks for Subband Adaptive Systems

, 1998
This paper introduces a polyphase implementation and design of an oversampled K-channel generalized DFT (GDFT) filter bank, which can be employed for subband adaptive filtering, and therefore is required to have a low aliasing level in the subband ...

Learning algorithms for adaptive digital filtering [PDF]

, 1993
In this thesis, we consider the problem of parameter optimisation in adaptive digital filtering. Adaptive digital filtering can be accomplished using both Finite Impulse Response (FIR) filters and Infinite Impulse Response Filters (IIR) filters. Adaptive

Adaptive minimum bit-error-rate filtering

, 2004
Adaptive filtering has traditionally been developed based on the minimum mean square error (MMSE) principle and has found ever-increasing applications in communications. The paper develops adaptive filtering based on an alternative minimum bit error rate

Requirements for an Adaptive Multimedia Presentation System with Contextual Supplemental Support Media [PDF]

, 2009
Investigations into the requirements for a practical adaptive multimedia presentation system have led the writers to propose the use of a video segmentation process that provides contextual supplementary updates produced by users.

Robust H infty filtering for uncertain differential linear repetitive processes

, 2008
The unique characteristic of a repetitive process is a series of sweeps or passes through a set of dynamics defined over a finite duration known as the pass length.
