Claim One:
1. A computer-implemented method of providing navigation directions, comprising: receiving a query image that includes a representation of a physical map captured by a camera of a computing device; determining, using a feature extraction algorithm, at least one first feature vector for the physical map represented in the query image; determining, using the feature extraction algorithm, at least one annotation that is marked on the physical map represented in the query image; comparing the at least one first feature vector from the physical map to a set of second feature vectors for map information of a map application; determining matching map information based at least in part upon the at least one first feature vector matching at least one second feature vector of the set of second feature vectors, the matching map information including geographic location information; determining a set of feature points corresponding to the at least one annotation; determining a geographic relationship between the set of feature points and the geographic location information; determining a set of navigation instructions based at least in part on the geographic relationship; and based at least in part upon a current location of the computing device and the set of navigation instructions, displaying on the computing device a determined route from the current location to an identified location in the query image.
