Biochemistry and medicine Automated identification of Fetal Heart Rate acceleration combined with fetal movement

In general, the currently-used acceleration identification algorithms are on the basis of FHR baseline. Once the baseline has been estimated, accelerations can be recognized consequently. However, it brings a circular problem. Baseline is by definition determined after accelerations and decelerations exclusion [1], but accelerations and decelerations are identified depending on baseline estimation in practice. Therefore, acceleration identification previous baseline recognition should be a solution.
