Signal threshold filter

WebThe signal-dependent rank order mean (SD-ROM) filter is effective at removing high levels of impulse noise from 2-D scalar-valued signals. Excellent results have been presented for both a two-state and a multi-state version of the filter. However, implementation of the two-state SD-ROM filter requires the selection of a set of threshold values. We propose a method … WebThe threshold is a value that the signal must be above before the system will call a pulse an ‘event’. If one enforces a threshold, the resulting pulse would look like this: Figure 2: Stylized signal with a threshold added. This threshold now reduces the signal from over 50 events down to just two. A much more manageable file size and ...
