An adaptive nearest neighbor multichannel filter
This paper addresses the problem of noise attenuation for multichannel data. The proposed filter utilizes adaptively determined data-dependent coefficients based on a novel distance measure which combines vector directional with vector magnitude filtering. The special case of color image processing is studied as an important example of multichannel signal processing. [l] R. Hopkins, “Digital te...
متن کاملAn Interference Cancelling Multichannel Matched Filter
We consider mobile radio communications with one user of interest and possibly interfering users and noise, over several discrete-time channels obtained either by oversampling or from multiple antennas. The optimal receiver structure for one signal of interest plus spatially and temporally correlated noise is MLSE equalization with an appropriately weighted metric for vector signals. We show ho...
متن کاملour multichannel filter
Conclusions: In this Letter, I have presented a resistive network using a feedback mechanism able to extract phase information from an image for depth evaluation. The information, related to a single frequency, can be properly organised by a further network, or the resistive network itself can be tuned to a more complex behaviour (e.g. regularisation of data). The design of this network makes s...
متن کاملMultichannel distance filter
A nonlinear multichannel digital filter is presented in this correspondence. The output is a weighted sum of all samples in the filter window, with a single parameter controlling the filter nonlinearity. Although input data ordering is not required, performance can surpass the performance of other ordering-based multichannel filters.
متن کاملReduction of Microphone Leakage Using Multichannel Wiener Filter
Microphone leakage is one of the most prevalent problems in audio applications involving multiple instruments and multiple microphones. Currently, sound engineers have limited solutions available to them. In this paper, the applicability of two widely used signal enhancement methods to this problem is discussed, namely blind source separation and noise suppression. By extending previous work, i...
