Noise reduction for periodic signals using high-resolution frequency analysis
The spectrum subtraction method is one of the most common methods by which to remove noise from a spectrum. Like many noise reduction methods, the spectrum subtraction method uses discrete Fourier transform (DFT) for frequency analysis. There is generally a trade-off between frequency and time resolution in DFT. If the frequency resolution is low, then the noise spectrum can overlap with the si...
متن کاملAnalysis and Separation of Audio Signals using High Frequency Resolution
Signature Advisor Date 2 Introduction As computers are becoming more frequently involved with the everyday uses of music, there is a need to recognize and identify the individual instruments. Whether analyzing recorded music or a live performance, there are two main tasks to the recognition of music, the separation of multiple instruments and the identification of each after it has been separat...
متن کاملNoise Reduction Using Multi-resolution Edge Analysis
In this paper, a new noise reduction algorithm is proposed. In general, an edge—high frequency information in an image—would be filtered or suppressed after image smoothing. The noise would be attenuated, but the image would lose its sharp information. This defect makes the post-processing harder. One new algorithm performs connectivity analysis on edge-data to make sure that only isolated edge...
متن کاملSelf-Adaptive Morphological Filter for Noise Reduction of Partial Discharge Signals
Partial Discharge assessment in the insulation of high voltage equipment is one of the most popular approaches for prevention of the insulation breakdown. In the procedure of thisassessment, noise reduction of partial discharge signals to get the original PD signal for accurate evaluation is inevitable. This denoising process shall be carried out such a way that the main features of the p...
متن کاملAdaptive Optimum Notch Filter for Periodic Noise Reduction in Digital Images
Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
