Abstract. Removing noise from audio signals requires a nondiagonal processing of time-frequency coefficients to avoid producing ldquomusical noise.rdquo State of the art algorithms perform a parameterized filtering of spectrogram coefficients with empirically fixed parameters. A block thresholding estimation procedure is introduced, which adjusts all parameters adaptively …

This paper introduces a new nondiagonal audio denoising algorithm through adaptive time-frequency block thresholding [60]. Block thresholding has been introduced by Cai and Silverman in mathematical statistics [4]–[6] to improve the asymptotic decay of diagonal thresholding estimators. For audio time-frequency denoising, we show that block ...

denoising is used to remove the noise while retaining as much as possible the important signal features. The purpose of image denoising is to estimate the original image from the noisy data. degrading . Denoising is more significant than any other tasks in image processing, analysis and applications. Preserving the details

As illustrated in Fig. 1, our proposed method is based on the following stages: First stage (basic estimate), we group the block-matching in the noisy image for every reference block and apply the adaptive thresholding. Unlike the conventional hard thresholding, which was adopted by BM3D filter, in the adaptive thresholding technique that our proposed scheme …
