Object grasping and manipulation is a crucial part of daily human activities. The study of these actions represents a central component in the development of systems that attempt to understand human activities and robots that are able to act in human environments.
Three essential parts of this problem are tackled in this talk: the perception of the human hand in interaction with objects, the modeling of human grasping actions and the refinement of the execution of a robotic grasp. The estimation of the human hand pose is carrried out with a markerless visual system that performs in real time under object occlusions. Low dimensional models of various grasping actions are created by exploiting the correlations between different hand joints in a non-linear manner with Gaussian Process Latent Variable Models (GPLVM). Finally, robot grasping actions are perfected by exploiting the appearance of the robot during action execution.
