Abstract:
We address in this thesis the problem of gesture recognition with specific focus on providing a
flexible model for movement trajectories as well as for estimating the variation in execution that
is inherently present when performing gestures. Gestures are captured in a computer vision scenario
which approaches somewhat the specifics of interactive surfaces. We propose a flexible model for gesture
commands based on a spline representation which is enhanced with elastic properties in a direct analogy
with the theory of elasticity from classical physics. The model is further used for achieving gesture
recognition in the context of supervised learning. In order to address the problem of variability in
execution, we propose a model that measures objectively and quantitatively the local tendencies that
users introduce in their executions. We make use of this model in order to address a problem that is
considered hard by the community: automatic segmentation of continuous motion trajectories and scale
invariant identification of gesture commands. We equally show the usefulness of our model for performing
ergonomic analysis on gesture dictionaries.
Keywords: gesture interfaces, elastic splines, variation in execution, trajectory segmentation.
