摘要：
This paper describes different algorithms that perform online pathological tremor characterization in terms of acceleration. Two distinct parametric models are used, an Auto-Regressive (AR) model and an harmonic model. Both models are recursively estimated with Extended Kalman Filters (EKFs). Experimental data was obtained with low cost sensors and the results are compared in terms of spectrogram estimation and prediction performance.
