public class BracketedAccelerometerIntervalDetectorThresholdFactorOptimizer
extends AccelerometerIntervalDetectorThresholdFactorOptimizer

Optimizes the threshold factor for interval detection of accelerometer data based on results of calibration. Only accelerometer calibrators based on unknown orientation are supported (in other terms, calibrators must be AccelerometerNonLinearCalibrator and must support AccelerometerCalibratorMeasurementType.STANDARD_DEVIATION_BODY_KINEMATICS). This implementation uses a BracketedSingleOptimizer to find the threshold factor value that minimizes Mean Square Error (MSE) for calibration parameters.
