Ridge and Danijel Sko\v{c}aj and Ale\v{s} Leonardis}, abstract = {Affordance learning has, in recent years, been generating heightened interest in both the cognitive vision and developmental robotics communities. In this paper we describe the development of a system that uses a robotic arm to interact with household objects on a table surface while observing the interactions using camera systems. Various computer vision methods are used to derive, firstly, object property features from intensity images and range data gathered before interaction and, subsequently, result features derived from video sequences gathered during and after interaction. We propose a novel affordance learning algorithm that automatically discretizes the result feature space in an unsupervised manner to form affordance classes that are then used as labels to train a supervised classifier in the object property feature space. This classifier may then be used to predict affordance classes, grounded in the result space, of novel objects based on object property observations.}, title = {Unsupervised Learning of Basic Object Affordances from Object Properties}, pages = {21-28}, year = {2009}, booktitle = {Proceedings of the Fourteenth Computer Vision Winter Workshop (CVWW)} }
