Directional motion-compensated spatio-temporal fuzzy filtering for quality enhancement of compressed video sequences
We propose a directional fuzzy lter to enhance the quality of compressed video sequences. A motion compensated spatiotemporal lter (MCSTF) is applied to intra-frame and inter-fram...

Novel schemes for nonlinear acoustic echo cancellation based on filter combinations
Nonlinear acoustic echo cancellers (NLAEC) are becoming increasingly important in hands-free applications. However, in some situations, an NLAEC is inferior to a linear AEC, espec...

Data-driven online variational filtering in wireless sensor networks
In this paper, a data-driven extension of the variational algorithm is proposed. Based on a few selected sensors, target tracking is performed distributively without any informati...

Spatially-Variant Anisotropic Morphological Filters Driven by Gradient Fields
Abstract. This paper deals with the theory and applications of spatially-variant mathematical morphology. We formalize the definition of spatially variant dilation/erosion and ope...

Flexible Filter Bank Dimensioning for Multicarrier Modulation and Frequency Domain Equalization
— This paper investigates both transmultiplexer (TMUX) and analysis-synthesis filter banks where the two sides of the filter bank system are of different sizes. Such configura...
