Abstract
This disclosure describes techniques for removing noise from a signal to generate a modified signal, with the modified signal preserving any transitions of interest (e.g., sharp-edge discontinuities) present within the initial signal. In one example, the signal comprises a time-series signal with the time series representing a sequence of weight measurements from a scale device. In some examples, the scale device includes a platform that supports one or more physical items that may be selectively removed or added to. Here, the signal may include a sequence of step functions corresponding to changes in weight on the scale device (based on the removal or addition of items on the platform), plus corrupting noise from vibration. The techniques described herein may remove the corrupting noise, while preserving the sharp edges representing sudden changes in weight.
