Shape-order context descriptor computation and matching. (a) and (b) Normalized trajectory of two gestures. (c) Diagram of log-polar histogram bins used in computing the shape-order contexts. (d), (e), and (f) Example of shape-order contexts for three reference samples. Note the visual similarity of (d) and (e) is much higher than (f).
