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

- Curve fitting using least-squares method is presented with resource usage outline.
- Method of gesture detection without begin and end markers is proposed.
- Concludes with visualization of gesture detection.

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 Bézier 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.
