Image denoising algorithm based on independent component analysis is proposed. The standard independent component analysis algorithm require that the number of sensors is more than or equal to that of sources, so it is impossible to apply independent component analysis to single channel image denoising directly. In this paper, a single channel image denoising algorithm is proposed by constructing...
Online monitoring system is usually used in different environments and thus is being exposed to different noise levels with characteristics not completely known. Therefore, digital processing algorithms are preferable than analogue filters to extract partial discharge (PD) pulses. The wavelet transform (WT) is a powerful tool for signal analysis and filtering due to its multiresolution characteristics...
