Abstract
Kalman filtering, including a model of system dynamics, is used to identify flash artifact. The Kalman filtering predicts the velocity or powers based on a past sequence of velocity or power. The prediction defines a confidence interval. Any current measures surpassing the confidence interval are identified as flash artifact and suppressed.
