Motion artifacts

The stress Electrocardiogram (ECG) gives more efficient results for the diagnosis of cardiovascular diseases, which may not be apparent when the patients are at rest. However, the noise produced by the movement of the patient and the environment often contaminates the ECG signal.

In this paper, we present a new approach for PPG based heart rate monitoring. We first perform the variational mode decomposition to decompose the PPG signal into multiple modes then eliminate the modes whose frequencies coincides with those from accelerator signals. Finally, the spectral analysis step is applied to estimate the spectrum of the signal and selects the spectral peaks corresponding to heart rate. Experimental results on a public available dataset recorded from 12 subjects during fast running validate the performance of the proposed algorithm.

In pursuit of a more engaging experience, one might be tempted to sit closer to a 2K presentation. But moving closer than 3.16 PH causes unwanted on-screen artifacts to become more obvious. The illusion of a continuous image begins to break down as individual pixels become evident. Subjects that present fine detail such as motion picture credits will appear especially rough. Image diagonals will appear jagged. And gaps between the pixels may also become visible. This is called “screen door effect” because viewing the movie becomes like looking through a screen door. ...
