Abstract: A computer-implemented data processing method to improve information quality in data sequences by attenuating noise in the data sequences, the method including: receiving input data sequences, having a plurality of elements, from one or more sensors, each of the elements having at least one dimensional component; performing a spectral analysis on the dimensional component of each of the elements, independently, to estimate a signal profile of the input data sequences; estimating a noise profile of the input data sequences using calibration data associated with the sensor; dynamically calculating a time-constant for a noise attenuation filter, and adapting the time-constant over time, for each one of the elements in the input data sequences, based on the relationship between the noise profile and the signal profile; applying the noise attenuation filter for each one of the elements to each one of the elements, respectively, to filter the input data sequences to derive filtered data sequences; and outputting the filtered data sequences.
