Humans usually associate an upright orientation with objects, plac ing them in a way that they are most commonly seen in our sur roundings. While it is an open challenge to recover the function ality of a shape from its geometry alone, this paper shows that it is often possible to infer its upright orientation by analyzing its geometry. Our key idea is to reduce the twodimensional (spher ical) orientation space to a small set of orientation candidates using functionalityrelated geometric properties of the object, and then determine the best orientation using an assessment function of sev eral functional geometric attributes defined with respect to each candidate. Specifically we focus on obtaining the upright orienta tion for manmade objects that typically stand on some flat surface (ground, floor, table, etc.), which include the vast majority of ob jects in our everyday surroundings. For these types of models ori entation candidates can be defined according to static equilibrium. For each candidate, we introduce a set of discriminative attributes linking shape to function. We learn an assessment function of these attributes from a training set using a combination of Random For est classifier and

classifier. Experiments demonstrate that our method generalizes well and achieves about 90%
prediction accuracy
for both a 10fold crossvalidation over the training set and a validation with an independent test set.
