Hyperspectral Mixed Gaussian and Sparse Noise Reduction
IEEE Geoscience and Remote Sensing Letters, 2020Hyperspectral images (HSIs) are often degraded by different noise types such as Gaussian and sparse noise. In this letter, a hyperspectral mixed Gaussian and sparse noise reduction technique, the HyMiNoR, is proposed.

A Survey of Active EMI Filters for Conducted EMI Noise Reduction in Power Electronic Converters
IEEE transactions on electromagnetic compatibility (Print), 2019Wide bandgap devices enable high power density power converters. Despite the advantages of increased switching frequency, the passive components are still a major bottleneck toward enabling high power density.

In this Letter, we propose a fast speckle noise reduction method with only a single reconstructed image based on convolutional neural networks. The proposed network has multi-sized kernels that can capture the speckle noise component effectively from ...

Noise reduction for vocal pathologies
Medical Engineering & Physics, 2002A noise reduction scheme, particularly suited for the correction of vocal pathologies, is proposed. The filter makes use of concepts originated within the theory of dynamical systems and deterministic chaos. In particular, the idea of embedding scalar data in order to reconstruct a phase space is of fundamental importance here. Furthermore, the concept

A noise-suppression circuit (10) divides the signal from a microphone (12) into a plurality of frequency sub-bands by means of a noise-band divider (18) and a subtraction circuit (36). By means of gain circuits (32) and (34), it applies separate gains to the separate bands and then recombines them in a signal combiner (38) to generate an output signal ...

Publisher Summary This chapter explains electrical noise theory and practical ways to reduce it in circuits. All electrical noise is created by the changing power of a circuit. Electronic noise can be considered as both, transmit and receive problem. The susceptibility of our equipment to this unavoidable electronic noise that is left in our circuit ...

With a nonlinear RGB or LRGB image in hand, we now continue with post-processing. The degree of linear noise reduction applied previously (Chap. 12) will dictate how much nonlinear smoothing is required. As MultiscaleLinearTransform (MLT) does such an impressive job smoothing linear data, you may find that when sufficient signal has been collected ...

Noise and Noise Reduction in Supersonic Jets
2018This paper describes a novel noise reduction method for supersonic jets. It involves the injection of relatively small amounts of air into the diverging section of a convergent-divergent nozzle. The air is injected through a series of injectors that are aligned axially. The injected air diverts the jet core flow and forms “fluid inserts.” These inserts

Reducing the operating impact noise of a moving bins sorter of the type in which the bins of the sorter are sequentially incremented with a rotatable open mouthed "C" cam drive, where the open ends of the "C" cam on opposite sides of the open mouth provide operative bin engaging cam surfaces for engaging a cam engaging portion of the bins, without ...
