Action tremor analysis from ordinary video sequence.
This paper focuses on tremor frequency analysis from the video sequence. In order to analyse the video data, the signal needs to be extracted from the video using the intensity change of the local area in time. Next, the power spectral density is used for the frequency estimate from the signal. Finally the results obtained from the video are compared with one of the standard measuring techniques for tremors--accelerometers.
