An optimum microphone array post-filter for speech applications
This paper proposes a post-filtering estimation scheme for multichannel noise reduction. The proposed method extends and improves the existing Zelinski’s and, the most general and prominent, McCowan’s post-filtering methods that use the autoand crossspectral densities of the multichannel input signals to estimate the transfer function of the Wiener post-filter. A major drawback of these two spe...
متن کاملOptimum Cascaded Design for Speech Enhancement Using Kalman Filter
Speech enhancement is the process of eliminating noise and increasing the quality of a speech signal, which is contaminated with other kinds of distortions. This paper is on developing an optimum cascaded system for speech enhancement. This aim is attained without diminishing any relevant speech information and without much computational and time complexity. LMS algorithm, Spectral Subtraction ...
متن کاملOptimum Filter Design for Water Level Detection
Abstract This report proposes a design method of a digital filter to detect running water region in video signal. As a result of applying this filter, the water level of a river is automatically detected as a boundary between the land region and the water region. Conventional approaches have used the edge detector "vertically" to extract a horizontal line as running water surface. The frame "su...
متن کاملDesign of Optimum Linear Phase Low Pass Fir Filter Using Hybrid Pso and Gsa Evolutionary Algorithm
The digital filters play an important role in the field of science and technology. Due to phase linearity and stability digital FIR filters are used in number of applications. The various design technology are developed for the designing of the digital filters using evolutionary techniques like particle swarm optimization(PSO), genetic algorithm(GA), differential evolution(DE) etc. and the modi...
