Savitzy-Golay filterThresholdingWavelet TransformElectrocardiogram (ECG) has always been the most basic useful and low cost tool for diagnosis. Various kinds of noises can contaminate the ECG signals which lead to incorrect diagnosis. In this paper a new method is developed for removal of baseline ...
The Savitzky–Golay smoothing filter is a type of filter first described in 1964 by Abraham Savitzky and Marcel J. E. Golay.[1] The Savitzky-Golay method essentially performs a local polynomial regression (of degree k) on a distribution (of at least k+1 equally spaced points) to determine...

A denoising scheme for lung sounds, based on Savitzky-Golay (S-G) filter is proposed in this paper. The order and frame length of the SG filter is determined objectively using the Signal to Noise Ratio (SNR) and computational time as objective function. Maximum SNR is observed when the ...
This paper describes a new filter developed for real-time speckle reduction and coherence enhancement of medical ultrasound images. The new filter, referred to as the directional Savitzky-Golay (DSG) filter, is a two-dimensional weighted Savitzky-Golay filter enhanced with a mechanism for adjusting ...
An Empirical Evaluation of Savitzky-Golay (SG) Filter for Denoising ST SegmentIn this paper, we propose a robust multilead electrocardiogram (ECG) detection system based on a continuous wavelet transform (CWT). First of all, QRS complexes are detected. Then, boundaries (onset and end) of each...
This paper describes a novel filter which is a two-dimensional extension of the one-dimensional Savitzky-Golay filter. The new filter, referred to as ... C Chinrungrueng,A Suvichakorn - Nuclear Science Symposium Conference Record 被引量: 82发表: 2000年 Noise reduction in Raman spectra: Finit...
This paper is about the definition and effectiveness and fast implementation of a particular family of smoothing filters. These "Savitzky-Golay filters" are popular in spectroscopy. But to filter experts in other areas they are virtually unknown! Since the filters are constructed in a very natural...
What is a savitzky-golay filter? Recently, while reading a paper on heart rate monitoring using an accelerometer [1], I found myself asking the question posed by the above title. While searching for the answer, I discovered many things that seemed to be well known to ot... Schafer, R....
