Detection of gestures without begin and end markers by fitting into Bezier curves with least squares method

摘要

Gesture recognition is used to obtain natural way of device control. This paper describes a method of extracting predefined gestures from series of points without a marker, when the gesture begins or ends. Presents a way to fit points to Bezier curve with constant memory usage. The procedure is based on least-squares method. Concludes with usage of algorithm to detect loops in series of points.
