Accelerometer-based gesture recognition via dynamic-time warping, affinity propagation, & compressive sensing
We propose a gesture recognition system based primarily on a single 3-axis accelerometer. The system employs dynamic time warping and affinity propagation algorithms for training and utilizes the sparse nature of the gesture sequence by implementing compressive sensing for gesture recognition. A dictionary of 18 gestures or classes is defined and a database of over 3,700 repetitions is created ...
متن کاملFastDTW: Toward Accurate Dynamic Time Warping in Linear Time and Space
The dynamic time warping (DTW) algorithm is able to find the optimal alignment between two time series. It is often used to determine time series similarity, classification, and to find corresponding regions between two time series. DTW has a quadratic time and space complexity that limits its use to only small time series data sets. In this paper we introduce FastDTW, an approximation of DTW t...
متن کاملGesture Recognition using Skeleton Data with Weighted Dynamic Time Warping
With Microsoft’s launch of Kinect in 2010, and release of Kinect SDK in 2011, numerous applications and research projects exploring new ways in human-computer interaction have been enabled. Gesture recognition is a technology often used in human-computer interaction applications. Dynamic time warping (DTW) is a template matching algorithm and is one of the techniques used in gesture recognition...
متن کاملMulti-Dimensional Dynamic Time Warping for Gesture Recognition
We present an algorithm for Dynamic Time Warping (DTW) on multi-dimensional time series (MDDTW). The algorithm utilises all dimensions to find the best synchronisation. It is compared to ordinary DTW, where a single dimension is used for aligning the series. Both one-dimensional and multidimensional DTW are also tested when derivatives instead of feature values are used for calculating the warp...
متن کاملContinuous Time-Varying Gesture Segmentation by Dynamic Time Warping of Compound Gesture Models
A novel method is introduced to simultaneously recognize and segment time-varying human gestures from continuous video streams. Motion is represented by a 3D spatio-temporal surface based upon the evolution of a contour over time. The temporal endpoints of a gesture are estimated by Dynamically Time Warping the input sequence against a set of Compound Gesture Models, which are composed of the c...
