Abstract
A three-dimensional (3D) object may be represented by object data. The object data includes probability distributions that describe particular features on the 3D object. A probability distribution represents the value of local descriptors for the same feature as obtained from a plurality of images at different camera poses relative to the 3D object. A query image may be processed to determine features, and the query local descriptors of those features may be used to test against previously stored probability distributions. A combination of probability distributions that show a high probability of corresponding to the query local descriptors may be used to identify the 3D object appearing in the query image.
