Directional Dynamic Time Warping for Gesture Recognition
Hyo-Rim Choi, TaeYong Kim · 2017
In this study, we propose a modified dynamic time warping (DTW) algorithm that compares the sequences based on the direction of the gesture's movement. When comparing the gesture sequences, the proposed algorithm compares the movement direction and calculates the difference by the Euclidean Distance, and therefore reflects the characteristics of the gesture direction. The proposed method enhances the recognition performance compared to the original method as shown in the experiment.
