A Method for Recognizing a Sequence of Sign Language Word Represented in a Japanese Sign Language Sentence

Sagawa et al focus on gesture segmentation. They define potential segmentation points as the minima of hand velocity and large enough hand direction changes. These points are filtered for noise. They also determine whether the gesture is one or two handed by finding the ratio of hand velocities. Lastly, sentences are formed by scoring recognized word and transition combinations.

Discussion
Sagawa et al use essentially the same segmentation points (speed and curvature) that we've seen before. Determining the number of hands used is also straight forward (are they moving about the same speed?).
