Appearance-based Gesture recognition in the compressed domain

19 Feb 2019  ·  Shaojie Xu, Anvesha Amaravati, Justin Romberg, Arijit Raychowdhury ·

We propose a novel appearance-based gesture recognition algorithm using compressed domain signal processing techniques. Gesture features are extracted directly from the compressed measurements, which are the block averages and the coded linear combinations of the image sensor's pixel values. We also improve both the computational efficiency and the memory requirement of the previous DTW-based K-NN gesture classifiers. Both simulation testing and hardware implementation strongly support the proposed algorithm.
