Augmented skeletal joints for temporal segmentation of sign language actions
We present in this paper a novel solution for temporal segmentation of human gestures that takes advantage of the skeletal-joints streams offered by the Kinect sensor. Our contribution consist in introducing an improved skeletal representation and its usage in a multilayer motion delimitation that distinguishes the non-vocabulary actions. The evaluation of the solution is presented on a subset of the Chalearn Gesture Challenge (CGC) 2014 dataset. The obtained temporal segmentation is better than the CGC baseline methods and has proved to be important for the task of human-action recognition.
